Chemical Structure

5-Chlorothiazol-2-amine CAS 41663-73-4 chemical structure

Description

5-Chlorothiazol-2-amine (C3H3ClN2S) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

5-Chlorothiazol-2-amine (CAS 41663-73-4) is a high-purity analytical reference standard with the molecular formula C3H3ClN2S and a molecular weight of 134.59 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.

As a certified reference material (CRM), 5-Chlorothiazol-2-amine 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.
