N-Cyclopentyl-1-methyl-[1,2,4]triazolo[4,3-a]quinoxalin-4-amine CAS 113181-12-7

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.

N-Cyclopentyl-1-methyl-[1,2,4]triazolo[4,3-a]quinoxalin-4-amine (CAS 113181-12-7), molecular formula C15H17N5 and molecular weight 267.33 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-Cyclopentyl-1-methyl-[1,2,4]triazolo[4,3-a]quinoxalin-4-amine (C15H17N5) 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).

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.
