Chemical Structure

(S)-Methyl 2-oxothiazolidine-4-carboxylate CAS 88806-99-9 chemical structure

Description

The occurrence of (S)-Methyl 2-oxothiazolidine-4-carboxylate is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-Methyl 2-oxothiazolidine-4-carboxylate (CAS 88806-99-9) is a high-purity analytical reference standard with the molecular formula C5H7NO3S and a molecular weight of 161.18 g/mol.

Based on its molecular formula C5H7NO3S, (S)-Methyl 2-oxothiazolidine-4-carboxylate contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 161.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
