5,7-Dichloro-2-(trifluoromethyl)thiazolo[5,4-d]pyrimidine CAS 1683576-73-9

Description

The molecular framework of 5,7-Dichloro-2-(trifluoromethyl)thiazolo[5,4-d]pyrimidine (C6Cl2F3N3S) is characterized by a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system. 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).

5,7-Dichloro-2-(trifluoromethyl)thiazolo[5,4-d]pyrimidine (CAS 1683576-73-9), molecular formula C6Cl2F3N3S and molecular weight 274.05 g/mol, is a CATO reference standard with documented purity and traceability.

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), 5,7-Dichloro-2-(trifluoromethyl)thiazolo[5,4-d]pyrimidine 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.
