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.

FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

5-Bromo-3-fluorobenzene-1,2-diamine delivers a uniquely functionalized aromatic scaffold featuring both bromo and fluoro substituents flanking the diamine core. This electron-deficient platform enables direct coupling in cross-coupling reactions and facilitates the construction of complex heterocycles. The molecule's stability under standard conditions supports reliable integration into synthetic sequences requiring precise spatial control.

Application

5-Bromo-3-fluorobenzene-1,2-diamine serves as a versatile building block for heterocyclic synthesis, enabling efficient access to substituted indoles, quinolines, and other nitrogen-containing scaffolds. The ortho-diamine functionality facilitates cyclization reactions under mild conditions, while the bromo and fluoro substituents offer complementary sites for palladium-catalyzed cross-coupling and electrophilic substitution. Bench-stable and readily purified by recrystallization, it functions effectively in multi-step synthetic sequences requiring functional group tolerance and predictable reactivity.
