Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Lithium(1+) ion 5-tert-butyl-1,2,4-oxadiazole-3-carboxylate.
Lithium(1+) ion 5-tert-butyl-1,2,4-oxadiazole-3-carboxylate (CAS 2126162-44-3) is a high-purity analytical reference standard with the molecular formula C7H9N2O3Li and a molecular weight of 176.10 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Lithium(1+) ion 5-tert-butyl-1,2,4-oxadiazole-3-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 176.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Lithium(1+) ion 5-tert-butyl-1,2,4-oxadiazole-3-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.
