Description
As a certified reference material (CRM), (S)-3-Amino-1-methyl-3,4-dihydropyrido[3,4-b][1,4]oxazepin-2(1H)-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-1-methyl-3,4-dihydropyrido[3,4-b][1,4]oxazepin-2(1H)-one hydrochloride (CAS 2124262-59-3), molecular formula C9H11N3O2HCl and molecular weight 229.66 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, chlorine substitution, (S)-3-Amino-1-methyl-3,4-dihydropyrido[3,4-b][1,4]oxazepin-2(1H)-one hydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 229.66 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
