2-Chloro-6-(4-(2-chloro-4-nitrophenyl)buta-1,3-dien-1-yl)benzene-1-sulfonyl fluoride CAS 31368-31-7 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 2-Chloro-6-(4-(2-chloro-4-nitrophenyl)buta-1,3-dien-1-yl)benzene-1-sulfonyl fluoride.

2-Chloro-6-(4-(2-chloro-4-nitrophenyl)buta-1,3-dien-1-yl)benzene-1-sulfonyl fluoride (CAS 31368-31-7) is a high-purity analytical reference standard with the molecular formula C16H10Cl2FNO4S and a molecular weight of 402.22 g/mol.

2-Chloro-6-(4-(2-chloro-4-nitrophenyl)buta-1,3-dien-1-yl)benzene-1-sulfonyl fluoride (C16H10Cl2FNO4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 2-Chloro-6-(4-(2-chloro-4-nitrophenyl)buta-1,3-dien-1-yl)benzene-1-sulfonyl fluoride 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.
