Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Chloroimidazo[1,5-a]pyrido[3,2-e]pyrazine.
6-Chloroimidazo[1,5-a]pyrido[3,2-e]pyrazine (CAS 240815-50-3), molecular formula C9H5ClN4 and molecular weight 204.62 g/mol, is a CATO reference standard with documented purity and traceability.
6-Chloroimidazo[1,5-a]pyrido[3,2-e]pyrazine (C9H5ClN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 6-Chloroimidazo[1,5-a]pyrido[3,2-e]pyrazine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
