4-Bromocrotonic acid (CAS 13991-36-1) is a halogenated building block of formula C4H5BrO2, 164.99 g/mol.
On an sp3 carbon the halide competes between substitution and elimination, so the temperature of the step decides the outcome more than the leaving group does.
The formula C4H5BrO2 resolves to 4 carbons with 2 oxygens and one bromine. With 4 carbons the molecule is small enough to be lost to evaporation during a work-up, so the step is usually run closed.
Handling and storage
Keep in the dark and closed; the alcohol that forms on hydrolysis is the impurity that appears first.
Ordering
Packing 1kg / 25kg / 100kg, with the batch COA, the SDS and a specification sheet suitable for incoming inspection travelling with the lot.
