4-Chloro-N-(4-fluoro-3-methoxyphenyl)benzene-1-sulfonamide CAS 1881293-44-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Chloro-N-(4-fluoro-3-methoxyphenyl)benzene-1-sulfonamide.

CATO supplies 4-Chloro-N-(4-fluoro-3-methoxyphenyl)benzene-1-sulfonamide (CAS 1881293-44-2), a certified reference material (molecular formula C13H11ClFNO3S, MW 315.75 g/mol) for analytical method development and quality control.

Based on its molecular formula C13H11ClFNO3S, 4-Chloro-N-(4-fluoro-3-methoxyphenyl)benzene-1-sulfonamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 315.75 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

CATO manufactures 4-Chloro-N-(4-fluoro-3-methoxyphenyl)benzene-1-sulfonamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
