Chemical Structure

4-Chloro-3-(chlorosulfonyl)benzoic Acid-13C6 CAS 1329836-24-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 261.03 g/mol gives 4-Chloro-3-(chlorosulfonyl)benzoic Acid-13C6 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-Chloro-3-(chlorosulfonyl)benzoic Acid-13C6 (CAS 1329836-24-9), a certified reference material (molecular formula C[13C]6H4Cl2O4S, MW 261.03 g/mol) for analytical method development and quality control.

The molecular framework of 4-Chloro-3-(chlorosulfonyl)benzoic Acid-13C6 (C[13C]6H4Cl2O4S) is characterized by a sulfone group, a carboxylic acid group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.

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.
