Chemical Structure

21744-55-8 5-Methylsulfonyltetrazole C2H4N4O2S V4388 CAS 21744-55-8 chemical structure

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 21744-55-8 5-Methylsulfonyltetrazole C2H4N4O2S V4388 (CAS 21744-55-8), a certified reference material (molecular formula C2H4N4O2S, MW 148.14 g/mol) for analytical method development and quality control.

The molecular framework of 21744-55-8 5-Methylsulfonyltetrazole C2H4N4O2S V4388 (C2H4N4O2S) is characterized by an amide group, a sulfone group, a carboxylic acid 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures 21744-55-8 5-Methylsulfonyltetrazole C2H4N4O2S V4388 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.
