    HazMat Fee

    An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

    The shipment is processed through FedEx Ground under the Limited Quantity option.

    Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

    If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Description

1-Bromo-4-chlorobutane features a bromine atom at one terminus and a chlorine atom at the opposite end of a four-carbon chain, enabling dual functionalization in synthetic sequences. This bifunctional alkyl halide facilitates efficient coupling reactions and serves as a key intermediate in the construction of complex molecular architectures through stepwise substitution processes.

Application

1-Bromo-4-chlorobutane serves as a versatile dihalide building block for constructing functionalized aliphatic chains and heterocyclic scaffolds. Its complementary reactivity enables sequential functionalization via nucleophilic substitution, facilitating the synthesis of bioactive intermediates and polymer precursors. The molecule exhibits good bench stability and is amenable to purification by distillation or chromatography, supporting reliable use in standard synthetic workflows.
