(3R,5R)-Methyl 2-methyl-3-phenylisoxazolidine-5-carboxylate CAS 87190-48-5

Description

The occurrence of (3R,5R)-Methyl 2-methyl-3-phenylisoxazolidine-5-carboxylate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(3R,5R)-Methyl 2-methyl-3-phenylisoxazolidine-5-carboxylate (CAS 87190-48-5) is a high-purity analytical reference standard with the molecular formula C12H15NO3 and a molecular weight of 221.25 g/mol.

The molecular framework of (3R,5R)-Methyl 2-methyl-3-phenylisoxazolidine-5-carboxylate (C12H15NO3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
