Chemical Structure

[1,2,4]Triazolo[1,5-a]pyrazin-2-ylmethanamine CAS 1823939-18-9 chemical structure

Description

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.

[1,2,4]Triazolo[1,5-a]pyrazin-2-ylmethanamine (CAS 1823939-18-9), molecular formula C6H7N5 and molecular weight 149.15 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, [1,2,4]Triazolo[1,5-a]pyrazin-2-ylmethanamine (C6H7N5) contains a nitrile group, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 149.15 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
