Chemical Structure
Description
The occurrence of 1-Bromo-2-methyl-d3-propane-2,3,3,3-d4 is closely related to deuterium isotope labeling, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-Bromo-2-methyl-d3-propane-2,3,3,3-d4 (CAS 344299-41-8), a certified reference material (molecular formula C4H2D7Br, MW 144.06 g/mol) for analytical method development and quality control.
The molecular framework of 1-Bromo-2-methyl-d3-propane-2,3,3,3-d4 (C4H2D7Br) is characterized by deuterium isotope labeling, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
