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

tert-Butyl (4-bromo-3-chlorophenyl)carbamate features a bromo-chloro-substituted phenyl core with a bench-stable carbamate protecting group. This orthogonal functionality enables selective deprotection in late-stage synthesis, particularly in the construction of complex pharmaceutical intermediates. The steric bulk of the tert-butyl moiety enhances stability during purification and reaction sequencing.

Application

tert-Butyl (4-bromo-3-chlorophenyl)carbamate serves as a versatile building block in medicinal chemistry, enabling the introduction of a bromo-chloro-substituted aniline motif under standard coupling conditions. The carbamate group provides excellent bench stability and facilitates straightforward deprotection to yield the free amine. Its compatibility with palladium-catalyzed cross-couplings and tolerance for diverse functional groups make it ideal for constructing complex heterocyclic scaffolds and API intermediates.
