CATO supplies .beta.,.beta.-Dimethylvinylbromide 1-Bromo-2-methyl-1-propene 1-Bromo-2-methylpropene 1-Propene, 1-bromo-2-methyl- 2-Methyl-1-propenyl bromide 3017-69-4 Isocrotyl bromide NSC-148224 NSC148224 Propene, 1-bromo-2-methyl- (CAS 3017-69-4), a certified reference material (molecular formula C4H7Br, MW 135.00 g/mol) for analytical method development and quality control.
Structurally, .beta.,.beta.-Dimethylvinylbromide 1-Bromo-2-methyl-1-propene 1-Bromo-2-methylpropene 1-Propene, 1-bromo-2-methyl- 2-Methyl-1-propenyl bromide 3017-69-4 Isocrotyl bromide NSC-148224 NSC148224 Propene, 1-bromo-2-methyl- (C4H7Br) contains 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 135.00 g/mol, it falls into the low-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.
