6-Chloro-[1,2,3,4]tetrazolo[1,5-b]pyridazine CAS 21413-15-0 chemical structure

Description

The occurrence of 6-Chloro-[1,2,3,4]tetrazolo[1,5-b]pyridazine is closely related to a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 6-Chloro-[1,2,3,4]tetrazolo[1,5-b]pyridazine (CAS 21413-15-0), a certified reference material (molecular formula C4H2ClN5, MW 155.55 g/mol) for analytical method development and quality control.

The molecular framework of 6-Chloro-[1,2,3,4]tetrazolo[1,5-b]pyridazine (C4H2ClN5) is characterized by a nitrile group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 6-Chloro-[1,2,3,4]tetrazolo[1,5-b]pyridazine 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.
