Chemical Structure

2,3-Dimethyl-6,7-dihydro-5H-cyclopenta[b]pyrazine CAS 38917-63-4 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

2,3-Dimethyl-6,7-dihydro-5H-cyclopenta[b]pyrazine (CAS 38917-63-4) is a high-purity analytical reference standard with the molecular formula C9H12N2 and a molecular weight of 148.20 g/mol.

The molecular framework of 2,3-Dimethyl-6,7-dihydro-5H-cyclopenta[b]pyrazine (C9H12N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
