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 2H-Benzo[e][1,2,4]thiadiazine-3-carboxylic acid 1,1-dioxide.
2H-Benzo[e][1,2,4]thiadiazine-3-carboxylic acid 1,1-dioxide (CAS 57864-78-5) is a high-purity analytical reference standard with the molecular formula C8H6N2O4S and a molecular weight of 226.21 g/mol.
The molecular framework of 2H-Benzo[e][1,2,4]thiadiazine-3-carboxylic acid 1,1-dioxide (C8H6N2O4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. 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 2H-Benzo[e][1,2,4]thiadiazine-3-carboxylic acid 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.
