Chemical Structure
Description
As a certified reference material (CRM), (R)-2-Phenyl-4,5-dihydrooxazole-4-methanol 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.
(R)-2-Phenyl-4,5-dihydrooxazole-4-methanol (CAS 82936-49-0), molecular formula C10H11NO2 and molecular weight 177.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (R)-2-Phenyl-4,5-dihydrooxazole-4-methanol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 177.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
