3-(1h-1,2,3,4-Tetrazol-1-yl)benzene-1-sulfonamide CAS 326873-69-2 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 3-(1h-1,2,3,4-Tetrazol-1-yl)benzene-1-sulfonamide.

CATO supplies 3-(1h-1,2,3,4-Tetrazol-1-yl)benzene-1-sulfonamide (CAS 326873-69-2), a certified reference material (molecular formula C7H7N5O2S, MW 225.23 g/mol) for analytical method development and quality control.

3-(1h-1,2,3,4-Tetrazol-1-yl)benzene-1-sulfonamide (C7H7N5O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), 3-(1h-1,2,3,4-Tetrazol-1-yl)benzene-1-sulfonamide 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.
