Chemical Structure
Description
The occurrence of (2-Aminothiazol-4-yl)methyl carbamimidothioate dihydrochloride is closely related to a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2-Aminothiazol-4-yl)methyl carbamimidothioate dihydrochloride (CAS 20167-22-0), molecular formula C5H8N4S2HCl and molecular weight 224.72 g/mol, is a CATO reference standard with documented purity and traceability.
(2-Aminothiazol-4-yl)methyl carbamimidothioate dihydrochloride (C5H8N4S2HCl) contains a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), (2-Aminothiazol-4-yl)methyl carbamimidothioate dihydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
