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

4-Bromo-5-chlorobenzene-1,2-diamine offers a dual halogenated aromatic scaffold with strategically positioned amino groups, enabling precise coupling in heterocyclic synthesis. This electron-deficient diamine integrates readily into advanced pharmaceutical intermediates and functional materials, providing high reactivity under standard conditions.

Application

4-Bromo-5-chlorobenzene-1,2-diamine serves as a versatile building block in medicinal chemistry and materials science, enabling the construction of heterocyclic scaffolds via cyclization or cross-coupling reactions. Its dual halogenated aryl functionality offers orthogonal reactivity for Pd-catalyzed transformations, while the diamine moiety provides sites for derivatization or coordination in catalytic systems. Bench-stable and readily purified by recrystallization, it functions effectively in standard synthetic workflows requiring functional group tolerance and predictable regiochemistry.
