Chemical Structure

Ethyl (S)-3-hydroxybutyrate CAS 56816-01-4 chemical structure

Description

CATO supplies Ethyl (S)-3-hydroxybutyrate (CAS 56816-01-4), a certified reference material (molecular formula C6H12O3, MW 132.16 g/mol) for analytical method development and quality control.

Based on its molecular formula C6H12O3, Ethyl (S)-3-hydroxybutyrate 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 132.16 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.
