3-Chloro-4-(4-(2-chloro-4-nitrophenyl)buta-1,3-dien-1-yl)benzene-1-sulfonyl fluoride CAS 31368-25-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Chloro-4-(4-(2-chloro-4-nitrophenyl)buta-1,3-dien-1-yl)benzene-1-sulfonyl fluoride.

3-Chloro-4-(4-(2-chloro-4-nitrophenyl)buta-1,3-dien-1-yl)benzene-1-sulfonyl fluoride (CAS 31368-25-9) is a high-purity analytical reference standard with the molecular formula C16H10Cl2FNO4S and a molecular weight of 402.22 g/mol.

The molecular framework of 3-Chloro-4-(4-(2-chloro-4-nitrophenyl)buta-1,3-dien-1-yl)benzene-1-sulfonyl fluoride (C16H10Cl2FNO4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
