Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(3As,8ar)-2-(2,2-bis((s)-4-isopropyl-4,5-dihydrooxazol-2-yl)propyl)-3a,8a-dihydro-8h-indeno[1,2-d]oxazole (CAS 862605-48-9), molecular formula C25H33N3O3 and molecular weight 423.55 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (3As,8ar)-2-(2,2-bis((s)-4-isopropyl-4,5-dihydrooxazol-2-yl)propyl)-3a,8a-dihydro-8h-indeno[1,2-d]oxazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 423.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), (3As,8ar)-2-(2,2-bis((s)-4-isopropyl-4,5-dihydrooxazol-2-yl)propyl)-3a,8a-dihydro-8h-indeno[1,2-d]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.
