Methyl 4'-(chlorosulfonyl)-[1,1'-biphenyl]-3-carboxylate CAS 939761-08-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 4'-(chlorosulfonyl)-[1,1'-biphenyl]-3-carboxylate.

Methyl 4'-(chlorosulfonyl)-[1,1'-biphenyl]-3-carboxylate (CAS 939761-08-7) is a high-purity analytical reference standard with the molecular formula C14H11ClO4S and a molecular weight of 310.75 g/mol.

Structurally, Methyl 4'-(chlorosulfonyl)-[1,1'-biphenyl]-3-carboxylate (C14H11ClO4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 310.75 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.
