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 4-Hydroxy-5,6-dimethyl-2(1H)-pyridinone.
4-Hydroxy-5,6-dimethyl-2(1H)-pyridinone (CAS 84953-72-0), molecular formula C7H9NO2 and molecular weight 139.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4-Hydroxy-5,6-dimethyl-2(1H)-pyridinone is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 139.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
