CATO supplies 503-60-6 KMT7V9LLBR 1-Chloro-3-methyl-2-butene 2-Butene, 1-chloro-3-methyl- 1-Chloro-3-methylbut-2-ene gamma,gamma-Dimethylallyl chloride 3,3-Dimethylallyl chloride EINECS 207-972-7 HSDB 6129 3-Methyl-2-butenyl chloride 3-Methylcrotyl chloride Prenyl chloride UNII-KMT7V9LLBR (CAS 503-60-6), a certified reference material (molecular formula C5H9Cl, MW 104.58 g/mol) for analytical method development and quality control.
Structurally, 503-60-6 KMT7V9LLBR 1-Chloro-3-methyl-2-butene 2-Butene, 1-chloro-3-methyl- 1-Chloro-3-methylbut-2-ene gamma,gamma-Dimethylallyl chloride 3,3-Dimethylallyl chloride EINECS 207-972-7 HSDB 6129 3-Methyl-2-butenyl chloride 3-Methylcrotyl chloride Prenyl chloride UNII-KMT7V9LLBR (C5H9Cl) contains chlorine 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 104.58 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.
