Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6a,7,8,9-Tetrahydro-5H-pyrido[3,2-e]pyrrolo[1,2-a]pyrazin-6-one (CAS 91622-91-2), molecular formula C10H11N3O and molecular weight 189.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6a,7,8,9-Tetrahydro-5H-pyrido[3,2-e]pyrrolo[1,2-a]pyrazin-6-one (C10H11N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 6a,7,8,9-Tetrahydro-5H-pyrido[3,2-e]pyrrolo[1,2-a]pyrazin-6-one 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.
