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 2-Chloroimidazo[1,5-a]pyrido[3,2-e]pyrazin-6(5H)-one (CAS 240815-52-5), a certified reference material (molecular formula C9H5ClN4O, MW 220.62 g/mol) for analytical method development and quality control.
2-Chloroimidazo[1,5-a]pyrido[3,2-e]pyrazin-6(5H)-one (C9H5ClN4O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 2-Chloroimidazo[1,5-a]pyrido[3,2-e]pyrazin-6(5H)-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.
