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+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+

Description

2-Bromo-3-chloro-1,4-difluorobenzene features a highly functionalized aromatic core with halogen substituents positioned for orthogonal reactivity. This electron-deficient scaffold enables selective cross-coupling and transition-metal-catalyzed transformations under standard conditions. The strategic placement of bromine, chlorine, and fluorine atoms allows sequential functionalization in complex molecule synthesis. Bench-stable and moisture-tolerant, it serves as a versatile building block for pharmaceutical intermediates and advanced materials.

Application

2-Bromo-3-chloro-1,4-difluorobenzene serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling palladium-catalyzed cross-coupling reactions due to its complementary halogen reactivity profile. The ortho-bromo and meta-chloro substituents provide orthogonal functionalization sites, while the difluoro pattern enhances metabolic stability and modulates electronic properties. Bench-stable and amenable to purification by distillation or chromatography, it facilitates efficient access to complex aromatic scaffolds in multi-step syntheses.
