Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(1S,8aS)-octahydropyrrolo[1,2-a]pyrazine-1-carboxylic acid (CAS 273223-57-7), molecular formula C8H14N2O2 and molecular weight 170.21 g/mol, is a CATO reference standard with documented purity and traceability.
(1S,8aS)-octahydropyrrolo[1,2-a]pyrazine-1-carboxylic acid (C8H14N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
