Chemical Structure

2,4,6-trichlorothieno[2,3-d]pyrimidine CAS 1481569-71-4 chemical structure

Description

As a certified reference material (CRM), 2,4,6-trichlorothieno[2,3-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.

CATO supplies 2,4,6-trichlorothieno[2,3-d]pyrimidine (CAS 1481569-71-4), a certified reference material (molecular formula C6H9Cl3N2S, MW 247.57 g/mol) for analytical method development and quality control.

2,4,6-trichlorothieno[2,3-d]pyrimidine (C6H9Cl3N2S) 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.

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.
