Chemical Structure
Description
The occurrence of Oxo-piperazin-1-yl-acetic acid, 98% is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Oxo-piperazin-1-yl-acetic acid, 98% (CAS 691394-09-9), molecular formula C6H10N2O3 and molecular weight 158.16 g/mol, is a CATO reference standard with documented purity and traceability.
Oxo-piperazin-1-yl-acetic acid, 98% (C6H10N2O3) 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).
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.
