2-(2-Chloro-4-methylphenoxy)ethane-1-sulfonyl chloride CAS 1491047-24-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2-Chloro-4-methylphenoxy)ethane-1-sulfonyl chloride.

2-(2-Chloro-4-methylphenoxy)ethane-1-sulfonyl chloride (CAS 1491047-24-5), molecular formula C9H10Cl2O3S and molecular weight 269.14 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(2-Chloro-4-methylphenoxy)ethane-1-sulfonyl chloride (C9H10Cl2O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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. 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.

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.
