3′-Formyl[1,1′-biphenyl]-3-carboxylic acid CAS 222180-19-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3′-Formyl[1,1′-biphenyl]-3-carboxylic acid.

3′-Formyl[1,1′-biphenyl]-3-carboxylic acid (CAS 222180-19-0) is a high-purity analytical reference standard with the molecular formula C14H10O3 and a molecular weight of 226.23 g/mol.

Structurally, 3′-Formyl[1,1′-biphenyl]-3-carboxylic acid (C14H10O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 226.23 g/mol, it falls into the medium-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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
