Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 257.76 g/mol gives Chlorazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Chlorazine (CAS 580-48-3), molecular formula C11H20ClN5 and molecular weight 257.76 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Chlorazine (C11H20ClN5) is characterized by a nitrogen-containing heterocyclic scaffold, 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 Chlorazine 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.
