Chemical Structure

Methyl (S)-4-bromo-3-hydroxybutanoate CAS 88759-56-2 chemical structure

Description

CATO supplies Methyl (S)-4-bromo-3-hydroxybutanoate (CAS 88759-56-2), a certified reference material (molecular formula C5H9BrO3, MW 197.03 g/mol) for analytical method development and quality control.

Structurally, Methyl (S)-4-bromo-3-hydroxybutanoate (C5H9BrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 197.03 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
