Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
rac-(2R,3S)-2-(3-methyl-1,2,4-oxadiazol-5-yl)oxolan-3-amine hydrochloride (CAS 2044705-76-0), molecular formula C7H11N3O2HCl and molecular weight 205.64 g/mol, is a CATO reference standard with documented purity and traceability.
rac-(2R,3S)-2-(3-methyl-1,2,4-oxadiazol-5-yl)oxolan-3-amine hydrochloride (C7H11N3O2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
As a certified reference material (CRM), rac-(2R,3S)-2-(3-methyl-1,2,4-oxadiazol-5-yl)oxolan-3-amine hydrochloride 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.
