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

Description

1-Bromo-2,3-difluorobenzene is a fluorinated aryl halide featuring strategically positioned bromine and two adjacent fluorine substituents on the benzene ring. This combination imparts enhanced stability and tailored reactivity for cross-coupling processes. The electron-deficient aromatic core facilitates palladium-catalyzed transformations, while the difluoro substitution pattern enables precise control over regioselectivity. This compound serves as a key building block in the synthesis of pharmaceutical intermediates and functional materials.

Application

1-Bromo-2,3-difluorobenzene serves as a versatile building block in cross-coupling reactions, enabling the efficient construction of biaryl and heteroaryl scaffolds. Its dual fluorine substituents enhance electrophilic reactivity while maintaining bench stability, facilitating coupling with boron, tin, and zinc reagents under standard conditions. The molecule exhibits excellent functional group tolerance and is well-suited for late-stage diversification in medicinal chemistry and materials synthesis.
