2-methyl[1,2,4]triazolo[1,5-c]quinazoline-5-thiol CAS 875160-35-3

Description

The occurrence of 2-methyl[1,2,4]triazolo[1,5-c]quinazoline-5-thiol is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-methyl[1,2,4]triazolo[1,5-c]quinazoline-5-thiol (CAS 875160-35-3) is a high-purity analytical reference standard with the molecular formula C10H8N4S and a molecular weight of 216.26 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 2-methyl[1,2,4]triazolo[1,5-c]quinazoline-5-thiol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 216.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
