Chemical Structure
Description
5'-Phenyl-[1,1':3',1''-terphenyl]-2'-carboxylic acid (CAS 5732-17-2), molecular formula C25H18O2 and molecular weight 350.41 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5'-Phenyl-[1,1':3',1''-terphenyl]-2'-carboxylic acid (C25H18O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 350.41 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 5'-Phenyl-[1,1':3',1''-terphenyl]-2'-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
