Chemical Structure
Description
As a certified reference material (CRM), 1,2,3,3a,4,5-hexahydropyrrolo[1,2-a]quinoxaline 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.
1,2,3,3a,4,5-hexahydropyrrolo[1,2-a]quinoxaline (CAS 18019-17-5), molecular formula C11H14N2 and molecular weight 174.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,2,3,3a,4,5-hexahydropyrrolo[1,2-a]quinoxaline (C11H14N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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. 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.
