Description
Biphenyl (CAS 92-52-4), also known as diphenyl, bibenzene, and E230, is an aromatic hydrocarbon consisting of two linked benzene rings. Approved as a food additive under E-code E230, it is registered under REACH and assigned EC number 202-163-5.
In citrus post-harvest treatment, biphenyl functions as an antifungal agent by disrupting fungal cell membrane integrity, inhibiting mold growth on fruit surfaces during storage and transport. In polymer and plastics manufacturing, it serves as a heat-transfer fluid component and catalyst precursor, enabling controlled thermal processing at elevated temperatures.
Biphenyl is available in crystalline powder, crystal, and flake forms to suit different handling and dosing requirements. It complies with food-grade specifications under E230 and is supplied in accordance with REACH regulations. Standard packaging formats are available for industrial procurement under HS code 29029030.
