Chemical Structure
Description
4-{5h,6h,7h-[1,3]thiazolo[3,2-a]pyrimidin-3-yl}aniline (CAS 23223-88-3), molecular formula C12H13N3S and molecular weight 231.32 g/mol, is a CATO reference standard with documented purity and traceability.
4-{5h,6h,7h-[1,3]thiazolo[3,2-a]pyrimidin-3-yl}aniline (C12H13N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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-{5h,6h,7h-[1,3]thiazolo[3,2-a]pyrimidin-3-yl}aniline 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.
