Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 4-(3-hydroxypyridin-2-yl)benzoate.
CATO supplies Methyl 4-(3-hydroxypyridin-2-yl)benzoate (CAS 1261981-75-2), a certified reference material (molecular formula C13H11NO3, MW 229.23 g/mol) for analytical method development and quality control.
Based on its molecular formula C13H11NO3, Methyl 4-(3-hydroxypyridin-2-yl)benzoate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 229.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
