Chemical Structure

2,2-Dibromomalonic acid CAS 595-45-9 chemical structure

Description

Based on its molecular formula C3H2Br2O4, 2,2-Dibromomalonic acid contains a carboxylic acid group, an ether linkage, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 261.85 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO supplies 2,2-Dibromomalonic acid (CAS 595-45-9), a certified reference material (molecular formula C3H2Br2O4, MW 261.85 g/mol) for analytical method development and quality control.

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.
