Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Lithium 5-(pyridin-3-yl)oxazole-2-carboxylate.
Lithium 5-(pyridin-3-yl)oxazole-2-carboxylate (CAS 857334-88-4), molecular formula C9H5N2O3Li and molecular weight 196.09 g/mol, is a CATO reference standard with documented purity and traceability.
Lithium 5-(pyridin-3-yl)oxazole-2-carboxylate (C9H5N2O3Li) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Lithium 5-(pyridin-3-yl)oxazole-2-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.
