Biphenyl is an organic compound consisting of two benzene rings linked directly, primarily used as a high-temperature solvent, in heat transfer fluids, and as a precursor in the synthesis of pharmaceuticals, dyes, and polymers. It appears as white crystalline flakes with a faint aromatic odor. This chemical has a CAS number of 92-52-4, a molecular formula of C12H10 (corrected from C6H5C6H5), and a molecular weight of 154.21 g/mol. It is stored at ambient conditions and carries a signal word of "Warning" for safety classification. Molekula supplies Biphenyl from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
