Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(S)-4-Benzyl-3-[2-(4-methoxyphenyl)acetyl]-2-oxazolidinone (CAS 143589-97-3) is a high-purity analytical reference standard with the molecular formula C19H19NO4 and a molecular weight of 325.36 g/mol.
(S)-4-Benzyl-3-[2-(4-methoxyphenyl)acetyl]-2-oxazolidinone (C19H19NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
