Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Diazoxide Impurity 1 Sodium Salt (CAS 84963-38-2), molecular formula C8H7ClNO4SNa and molecular weight 271.65 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a salt form, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Diazoxide Impurity 1 Sodium Salt is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 271.65 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).
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.
