Product categorization
Description
4-Bromo-1-butene [5162-44-7] is a clear to slightly yellow, volatile organic liquid with a characteristic odor. This versatile compound features both a terminal alkene and a primary alkyl bromide, making it a valuable intermediate in organic synthesis. The dual functionality enables a wide range of chemical transformations, including nucleophilic substitutions and metal-catalyzed reactions. While not a direct substrate for traditional Suzuki or Heck couplings, it serves as a useful building block in the synthesis of more complex molecules, including those used in pharmaceuticals, agrochemicals, and specialty chemicals.
We understand the varied demands of our customers. Therefore, we provide 3,3-Dimethyl-2-butanone in quantities from milligrams for research projects to multi-kilogram batches to ensure you receive the exact volume you need.
