Chemical Structure
Description
Ethyl 5-hydroxy-3-(4-methoxyphenyl)-2-methyl-5-(trifluoromethyl)-1,2-oxazolidine-4-carboxylate (CAS 321391-89-3), molecular formula C15H18F3NO5 and molecular weight 349.30 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Ethyl 5-hydroxy-3-(4-methoxyphenyl)-2-methyl-5-(trifluoromethyl)-1,2-oxazolidine-4-carboxylate (C15H18F3NO5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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 349.30 g/mol, it falls into the moderately-high-molecular-weight range. 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.
