Chemical Structure

6-Chloro-4-(2-fluorophenyl)-2H-benzo[e][1,2,3]thiadiazine 1,1-dioxide CAS 1031557-71-7 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 6-Chloro-4-(2-fluorophenyl)-2H-benzo[e][1,2,3]thiadiazine 1,1-dioxide.

6-Chloro-4-(2-fluorophenyl)-2H-benzo[e][1,2,3]thiadiazine 1,1-dioxide (CAS 1031557-71-7), molecular formula C13H8ClFN2O2S and molecular weight 310.73 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 6-Chloro-4-(2-fluorophenyl)-2H-benzo[e][1,2,3]thiadiazine 1,1-dioxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 310.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures 6-Chloro-4-(2-fluorophenyl)-2H-benzo[e][1,2,3]thiadiazine 1,1-dioxide 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.
