Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
3-Amino-4-oxohexahydro-2H-pyrrolo[2,1-b][1,3]oxazine-6-carboxylic acid (CAS 349101-93-5), molecular formula C8H12N2O4 and molecular weight 200.19 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Amino-4-oxohexahydro-2H-pyrrolo[2,1-b][1,3]oxazine-6-carboxylic acid (C8H12N2O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 200.19 g/mol, it falls into the medium-molecular-weight range. 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.
