Chemical Structure

3-Chloro-3'-methyl-[1,1'-biphenyl]-4-carboxylic acid CAS 1237103-23-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Chloro-3'-methyl-[1,1'-biphenyl]-4-carboxylic acid.

CATO supplies 3-Chloro-3'-methyl-[1,1'-biphenyl]-4-carboxylic acid (CAS 1237103-23-9), a certified reference material (molecular formula C14H11ClO2, MW 246.69 g/mol) for analytical method development and quality control.

The molecular framework of 3-Chloro-3'-methyl-[1,1'-biphenyl]-4-carboxylic acid (C14H11ClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
