Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-(Chloromethyl)-2,5-dimethyl-1,3-oxazole (CAS 777823-76-4), molecular formula C6H8ClNO and molecular weight 145.59 g/mol, is a CATO reference standard with documented purity and traceability.
4-(Chloromethyl)-2,5-dimethyl-1,3-oxazole (C6H8ClNO) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
As a certified reference material (CRM), 4-(Chloromethyl)-2,5-dimethyl-1,3-oxazole 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.
