3-Oxo-3,4-dihydro-2H-1,2,4-benzothiadiazine-7-carboxylic acid 1,1-dioxide CAS 201224-76-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Oxo-3,4-dihydro-2H-1,2,4-benzothiadiazine-7-carboxylic acid 1,1-dioxide.

3-Oxo-3,4-dihydro-2H-1,2,4-benzothiadiazine-7-carboxylic acid 1,1-dioxide (CAS 201224-76-2), molecular formula C8H6N2O5S and molecular weight 242.21 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Oxo-3,4-dihydro-2H-1,2,4-benzothiadiazine-7-carboxylic acid 1,1-dioxide (C8H6N2O5S) 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. 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.

CATO manufactures 3-Oxo-3,4-dihydro-2H-1,2,4-benzothiadiazine-7-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.
