Chemical Structure
Description
1-(Benzyloxy)-2-oxo-1,2-dihydropyridine-3-carboxylic acid (CAS 1225872-56-9) is a high-purity analytical reference standard with the molecular formula C13H11NO4 and a molecular weight of 245.23 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1-(Benzyloxy)-2-oxo-1,2-dihydropyridine-3-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 245.23 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).
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.
