Chemical Structure
Description
CATO supplies 2-((6-Methoxy-3-nitropyridin-2-yl)thio)propanoic acid (CAS 175205-01-3), a certified reference material (molecular formula C9H10N2O5S, MW 258.25 g/mol) for analytical method development and quality control.
Structurally, 2-((6-Methoxy-3-nitropyridin-2-yl)thio)propanoic acid (C9H10N2O5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 258.25 g/mol, it falls into the medium-molecular-weight range. 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.
