Description
As a certified reference material (CRM), (S)-3-Amino-6,8-difluoro-5-methyl-2,3-dihydrobenzo[b][1,4]oxazepin-4(5H)-one 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.
(S)-3-Amino-6,8-difluoro-5-methyl-2,3-dihydrobenzo[b][1,4]oxazepin-4(5H)-one hydrochloride (CAS 1622855-46-2), molecular formula C10H10F2N2O2HCl and molecular weight 264.66 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, (S)-3-Amino-6,8-difluoro-5-methyl-2,3-dihydrobenzo[b][1,4]oxazepin-4(5H)-one hydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.66 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.
