Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 140.04 g/mol gives 1-Bromo-2-methylpropane-3,3,3-d3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Bromo-2-methylpropane-3,3,3-d3 (CAS 344299-42-9), molecular formula C4H6D3Br and molecular weight 140.04 g/mol, is a CATO reference standard with documented purity and traceability.
1-Bromo-2-methylpropane-3,3,3-d3 (C4H6D3Br) contains deuterium isotope labeling, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
