Chemical Structure
Description
As a certified reference material (CRM), tert-Butyl trans-octahydropyrrolo[3,4-b][1,4]oxazine-6-carboxylate 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.
tert-Butyl trans-octahydropyrrolo[3,4-b][1,4]oxazine-6-carboxylate (CAS 138026-93-4), molecular formula C11H20N2O3 and molecular weight 228.29 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, tert-Butyl trans-octahydropyrrolo[3,4-b][1,4]oxazine-6-carboxylate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 228.29 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.
