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.

Type	HazMat Fee
Excepted Quantity	$0.00

Description

1,2-Diamino-3,4-difluorobenzene features two amino groups flanking a difluorinated aromatic core, enabling selective coupling in heterocyclic synthesis. The electron-deficient ring enhances reactivity in transition-metal-catalyzed cross-couplings, while the bench-stable nature supports reliable handling in process development workflows.

Application

1,2-Diamino-3,4-difluorobenzene serves as a versatile building block for fluorinated aromatic scaffolds in medicinal chemistry and materials science. Its ortho-diamino motif enables efficient coordination in metal complexes and facilitates cyclization reactions to access substituted quinazolines and other heterocyclic frameworks. The difluoro substitution enhances metabolic stability and modulates electronic properties, while the compound exhibits good bench stability and compatibility with standard coupling protocols.
