Chemical Structure
Description
3,4-Dihydropyrrolo[1,2-a]pyrazine (CAS 71257-37-9) is a high-purity analytical reference standard with the molecular formula C7H8N2 and a molecular weight of 120.15 g/mol.
The molecular framework of 3,4-Dihydropyrrolo[1,2-a]pyrazine (C7H8N2) is characterized by a nitrile group, an aromatic ring system. 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 3,4-Dihydropyrrolo[1,2-a]pyrazine 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.
