Chemical Structure

Butyl (S)-oxirane-2-carboxylate CAS 118623-63-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Butyl (S)-oxirane-2-carboxylate.

Butyl (S)-oxirane-2-carboxylate (CAS 118623-63-5), molecular formula C7H12O3 and molecular weight 144.17 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H12O3, Butyl (S)-oxirane-2-carboxylate contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 144.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
