5-Aminopyridine-2-thiol CAS 760117-50-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Aminopyridine-2-thiol.

CATO supplies 5-Aminopyridine-2-thiol (CAS 760117-50-8), a certified reference material (molecular formula C5H6N2S, MW 126.18 g/mol) for analytical method development and quality control.

Owing to a nitrile group, sulfur-containing functionality, 5-Aminopyridine-2-thiol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 126.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

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.
