Chemical Structure
Description
(2S)-piperidine-2-carbonitrile; oxalic acid (CAS 2173637-43-7), molecular formula C6H10N2C2H2O4 and molecular weight 200.19 g/mol, is a CATO reference standard with documented purity and traceability.
(2S)-piperidine-2-carbonitrile; oxalic acid (C6H10N2C2H2O4) 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 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.
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.
