Chemical Structure

1-(2-chloroethyl)-4-ethyl-4,5-dihydro-1H-1,2,3,4-tetrazol-5-one CAS 69049-03-2 chemical structure

Description

CATO supplies 1-(2-chloroethyl)-4-ethyl-4,5-dihydro-1H-1,2,3,4-tetrazol-5-one (CAS 69049-03-2), a certified reference material (molecular formula C5H11ClN4O, MW 178.62 g/mol) for analytical method development and quality control.

The molecular framework of 1-(2-chloroethyl)-4-ethyl-4,5-dihydro-1H-1,2,3,4-tetrazol-5-one (C5H11ClN4O) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 1-(2-chloroethyl)-4-ethyl-4,5-dihydro-1H-1,2,3,4-tetrazol-5-one 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.
