Cyclopropylmethyl Bromide ((bromomethyl)cyclopropane, CAS 7051-34-5), min. 98% GC, supplied wholesale by Zyntex. Alkylating building block for pharmaceutical synthesis, drug discovery and fine chemicals. CoA and SDS.
Cyclopropylmethyl bromide (C4H7Br) is a clear, colorless to pale yellow liquid that boils at about 105°C. It reacts with amines, phenols and other nucleophiles to attach a cyclopropylmethyl group.
In addition, pharmaceutical producers use it as an intermediate in the synthesis of several APIs that contain the cyclopropylmethyl group, for example certain opioid antagonists and respiratory medicines, and in drug discovery chemistry. Similarly, agrochemical and fine chemical researchers use it as a building block.
Because it is flammable and an alkylating agent, Zyntex supplies it only to industrial and research users with appropriate handling facilities. Related intermediates in our range include Bromoacetyl Bromide and Ethyl Bromide.
Typical uses include, for example:
💊 API Synthesis
Cyclopropylmethyl group introduction.
🔬 Drug Discovery
Medicinal chemistry building block.
🌾 Agrochemicals
Research synthesis.
⚗️ Fine Chemicals
Alkylating agent.
