Chemical Structure
Description
As a certified reference material (CRM), 2-(3-chlorophenyl)-1,3-thiazol-4-amine 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.
2-(3-chlorophenyl)-1,3-thiazol-4-amine dihydrochloride (CAS 2031258-68-9), molecular formula C9H7ClN2SHCl and molecular weight 247.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(3-chlorophenyl)-1,3-thiazol-4-amine dihydrochloride (C9H7ClN2SHCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
