Chemical Structure

2-Bromoisobutyric acid-2-hydroxyethyl ester CAS 189324-13-8 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 2-Bromoisobutyric acid-2-hydroxyethyl ester.

2-Bromoisobutyric acid-2-hydroxyethyl ester (CAS 189324-13-8) is a high-purity analytical reference standard with the molecular formula C6H11BrO3 and a molecular weight of 211.05 g/mol.

Structurally, 2-Bromoisobutyric acid-2-hydroxyethyl ester (C6H11BrO3) 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 211.05 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.
