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 (2R, 3R) -2-Bromo-3-hydroxybutanedioic Acid 1,4-Diethyl Ester.
CATO supplies (2R, 3R) -2-Bromo-3-hydroxybutanedioic Acid 1,4-Diethyl Ester (CAS 80640-15-9), a certified reference material (molecular formula C8H13BrO5, MW 269.09 g/mol) for analytical method development and quality control.
Structurally, (2R, 3R) -2-Bromo-3-hydroxybutanedioic Acid 1,4-Diethyl Ester (C8H13BrO5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 269.09 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.
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.
