Description

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 supplies 7H-Azepino[2,1-c][1,2,4]benzothiadiazine-3-carboxylic acid, 8,9,10,11-tetrahydro-, 5,5-dioxide (CAS 730992-36-6), a certified reference material (molecular formula C13H14N2O4S, MW 294.33 g/mol) for analytical method development and quality control.

7H-Azepino[2,1-c][1,2,4]benzothiadiazine-3-carboxylic acid, 8,9,10,11-tetrahydro-, 5,5-dioxide (C13H14N2O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.

As a certified reference material (CRM), 7H-Azepino[2,1-c][1,2,4]benzothiadiazine-3-carboxylic acid, 8,9,10,11-tetrahydro-, 5,5-dioxide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
