Description
3-Hydroxy-2-oxopropanoic acid lithium salt 3-Hydroxy-2-oxopropionic acid lithium salt 3369-79-7 Lithium |A-hydroxypyruvate hydrate |A-Hydroxypyruvic acid lithium salt hydrate (CAS 3369-79-7) is a high-purity analytical reference standard with the molecular formula C3H3O4H2OLi and a molecular weight of 128.01 g/mol.
3-Hydroxy-2-oxopropanoic acid lithium salt 3-Hydroxy-2-oxopropionic acid lithium salt 3369-79-7 Lithium |A-hydroxypyruvate hydrate |A-Hydroxypyruvic acid lithium salt hydrate (C3H3O4H2OLi) contains a carboxylic acid 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.
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.
