Chemical Structure

2-amino-3-chloro-pyridine-4-thiol CAS 2055759-39-0 chemical structure

Description

CATO manufactures 2-amino-3-chloro-pyridine-4-thiol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

2-amino-3-chloro-pyridine-4-thiol (CAS 2055759-39-0) is a high-purity analytical reference standard with the molecular formula C5H11ClN2S and a molecular weight of 166.67 g/mol.

Owing to sulfur-containing functionality, chlorine substitution, 2-amino-3-chloro-pyridine-4-thiol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
