Biphenyl Market Size
The global biphenyl market was valued at USD 290 million in 2025. The market is expected to grow from USD 305.8 million in 2026 to USD 505.5 million in 2035, at a CAGR of 5.7% according to latest report published by Global Market Insights Inc.
Biphenyl Market Key Takeaways
Market Leader: Eastman Chemical Company led with over 18.5% market share in 2025.
Leading Players: Top 5 players in this market include Eastman Chemical Company, BASF SE, Dow Inc., Merck KGaA, Mitsubishi Chemical Corporation, which collectively held a market share of 68% in 2025.
Biphenyl is a planar aromatic hydrocarbon consisting of two phenyl rings connected by a single carbon–carbon bond, produced industrially through the thermal dehydrogenation and coupling of benzene and as a co-product of toluene dealkylation [1]U.S. Environmental Protection Agency, Chemical Market Analysis: Biphenyl and Diphenyl Oxide Environmental Profile. nepis.epa.gov. The compound serves across multiple applications: as an intermediate in the synthesis of active pharmaceutical ingredients (APIs), agrochemicals, and high-performance polymers; as a core constituent of eutectic heat transfer fluids and, at ultra-high purity levels, as a building block for organic electronics, including OLED host matrices and liquid crystal compounds.
Asia Pacific dominates global biphenyl consumption, accounting for approximately 47.4% of market revenue in 2025 (USD 144.31 million), driven by China's extensive chemical synthesis base and India's pharmaceutical API expansion. The Middle East & Africa region, valued at USD 12.98 million in 2025, is forecast to expand at the fastest rate (7.20% CAGR through 2035), propelled by petrochemical complexes and concentrated solar power (CSP) thermal storage projects. North America holds the second-largest position at USD 72.27 million in 2025 (with the U.S. representing 88.5% of regional demand), followed by Europe at USD 60.10 million and Latin America at USD 14.44 million.
Market demand exhibits a structural bifurcation between high-volume technical grades and rapidly expanding premium-grade applications. Technical/industrial grade biphenyl, used primarily in heat transfer fluids and agrochemical synthesis, accounts for 44.7% of the 2025 market. Simultaneously, electronic/LCD and pharmaceutical/analytical grades command higher unit realizations and outpace commodity volume growth, supporting the overall 5.56% CAGR trajectory.
GMI Analyst View
The biphenyl market's acceleration from a historical 4.0% CAGR to 5.56% through 2035 is driven by qualitative demand shifts. Growth centers on two key areas: the premiumization of electronics-grade demand from OLED displays and semiconductor packaging, and sustained consumption in concentrated solar power (CSP) heat transfer fluids requiring long-duration thermal stability. Expanding pharmaceutical API synthesis—especially sartan antihypertensives and anti-inflammatory NSAIDs—further elevates demand for pharmaceutical-grade material.
Growth will remain paced by benzene feedstock volatility and Western regulatory compliance hurdles in the near term, before accelerating as Asian electronic supply chains and Middle Eastern CSP projects mature. Producers vertically integrated into aromatics or focused on certified high-purity grades will maintain stronger pricing power than unintegrated technical-grade suppliers.
Key Drivers
Rising pharmaceutical API production driving demand for high-purity intermediates
Biphenyl's symmetrical aromatic structure serves as a core molecular scaffold in active pharmaceutical ingredient (API) synthesis, particularly within the sartan antihypertensive class (such as losartan, valsartan, azilsartan, and candesartan) utilizing cyanobiphenyl intermediates [2]Beilstein Journal of Organic Chemistry, Efficient Synthesis of Sartan Intermediates via Cross-Coupling. beilstein-journals.org. Fluorinated biphenyl rings are also central to non-steroidal anti-inflammatory drugs (NSAIDs) like flurbiprofen [4]National Center for Biotechnology Information, PubChem Compound Summary: Flurbiprofen. pubchem.ncbi.nlm.nih.gov. Manufacturing these APIs requires pharmaceutical-grade biphenyl (99.8%+ purity) adhering to strict ICH Q3 impurity limits. The ongoing expansion of API synthesis in India and China directly sustains high-purity biphenyl consumption [5]U.S. Pharmacopeia, Global Active Pharmaceutical Ingredient Manufacturing Capacity Trends. qualitymatters.usp.org.
Growing adoption of biphenyl-based heat transfer fluids in industrial systems
The eutectic blend of 26.5% biphenyl and 73.5% diphenyl oxide (DPO) represents the industry benchmark for high-temperature synthetic organic heat transfer fluids (HTFs) [6. Operating in both liquid and vapor phases across a 12°C to 400°C window, this fluid delivers unmatched thermal stability in synthetic fiber manufacturing (PET, nylon), petrochemical processing, and parabolic trough concentrated solar power (CSP) facilities [8]Energies (MDPI), Assessment and Perspectives of Heat Transfer Fluids for Concentrated Solar Power. mdpi.com. High-purity HTF formulations resist thermal degradation 1.7 to 2.4 times longer than lower-grade alternatives, providing significant operational lifecycle savings for utility-scale CSP installations [9]Energy Procedia, Fluid Lifetime and Degradation Analysis of Biphenyl Grades in Solar Thermal Systems. sciencedirect.com.
Expanding high-performance polymer usage in electronics and aerospace
Biphenyl derivatives confer exceptional thermal and mechanical resistance when integrated into polymer chains. A prominent example is 3,3',4,4'-biphenyltetracarboxylic dianhydride (BPDA), a key monomer for polyimide films used in flexible electronics, circuit substrates, and aerospace components [10]Mitsubishi Chemical Corporation, BPDA Monomers and Biphenyl-Type Advanced Epoxy Resins. m-chemical.co.jp. Biphenyl-type epoxy resins also provide high heat resistance and low stress in semiconductor encapsulation. In organic electronics, biphenyl forms the core backbone of CBP and NPB host and transport materials utilized in high-efficiency OLED displays .
Key Restraints
Environmental regulations and legacy perception risks
While biphenyl is chemically distinct from toxic polychlorinated biphenyls (PCBs), regulatory frameworks enforce stringent controls to verify the total absence of chlorinated byproducts in production streams. Regulations such as EU REACH mandate extensive environmental fate documentation and chemical registration dossiers, imposing compliance costs that represent 3% to 8% of revenue for standard-grade suppliers.
Volatile benzene feedstock pricing
Because industrial biphenyl is synthesized directly via thermal dehydrogenation of benzene, production costs track crude oil and refinery aromatics pricing. Unhedged fluctuations in benzene spot prices introduce 12% to 18% annual input cost volatility, squeezing profit margins for unintegrated producers serving price-sensitive heat transfer fluid markets.
GMI Analyst View
Regulatory and feedstock pressures will accelerate market consolidation. Higher REACH compliance and testing costs disproportionately burden smaller regional producers, channeling volume toward major producers with dedicated regulatory platforms and integrated steam crackers.
