Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Sodium 2-thioxopyridin-1(2H)-olate.
CATO supplies Sodium 2-thioxopyridin-1(2H)-olate (CAS 15922-78-8), a certified reference material (molecular formula C5H4NOSNa, MW 149.14 g/mol) for analytical method development and quality control.
Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, Sodium 2-thioxopyridin-1(2H)-olate is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 149.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
