Chemical Structure
Description
7-Methyl-5,6,7,8-Tetrahydro-[1,2,4]Triazolo[1,5-a]pyrazin-2-Amine HCl (CAS 1956380-46-3), molecular formula C6H11N5HCl and molecular weight 189.65 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-Methyl-5,6,7,8-Tetrahydro-[1,2,4]Triazolo[1,5-a]pyrazin-2-Amine HCl (C6H11N5HCl) is characterized by a nitrile group, chlorine substitution. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
