Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(2,3,4-Trichlorophenyl)thiazol-2-amine.
4-(2,3,4-Trichlorophenyl)thiazol-2-amine (CAS 123971-41-5), molecular formula C9H5Cl3N2S and molecular weight 279.57 g/mol, is a CATO reference standard with documented purity and traceability.
4-(2,3,4-Trichlorophenyl)thiazol-2-amine (C9H5Cl3N2S) contains a nitrogen-containing heterocyclic scaffold, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 4-(2,3,4-Trichlorophenyl)thiazol-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.
