Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,4-Dichloro-5-((trifluoromethyl)thio)pyrimidine.
2,4-Dichloro-5-((trifluoromethyl)thio)pyrimidine (CAS 108222-71-5), molecular formula C5HCl2F3N2S and molecular weight 249.04 g/mol, is a CATO reference standard with documented purity and traceability.
2,4-Dichloro-5-((trifluoromethyl)thio)pyrimidine (C5HCl2F3N2S) contains a nitrile group, sulfur-containing functionality, fluorine/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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,4-Dichloro-5-((trifluoromethyl)thio)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.
