P-Terphenyl-4-carboxylic acid CAS 5731-15-7

Description

The occurrence of P-Terphenyl-4-carboxylic acid is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

P-Terphenyl-4-carboxylic acid (CAS 5731-15-7), molecular formula C19H14O2 and molecular weight 274.31 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, P-Terphenyl-4-carboxylic acid (C19H14O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 274.31 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 P-Terphenyl-4-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.
