Chemical Structure
Description
Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 4-Aminopyrimidine-5-carbothioamide hydrate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 172.21 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).
4-Aminopyrimidine-5-carbothioamide hydrate (CAS 256525-68-5) is a high-purity analytical reference standard with the molecular formula C5H6N4SH2O and a molecular weight of 172.21 g/mol.
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.
CATO manufactures 4-Aminopyrimidine-5-carbothioamide hydrate 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.
