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

Description

2-Bromo-1-chloro-3,5-difluorobenzene features a highly functionalized aromatic core with orthogonal halogen handles. This electron-deficient scaffold enables selective cross-coupling reactions under mild conditions, delivering complex fluorinated architectures with high regiocontrol. The molecule exhibits excellent stability and compatibility in Pd-catalyzed transformations.

Application

2-Bromo-1-chloro-3,5-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. The ortho-bromo and meta-chloro substituents provide regioselective functionalization options, while the difluoro pattern enhances metabolic stability and modulates electronic properties. Bench-stable and compatible with standard purification methods, it facilitates efficient construction of complex aryl scaffolds in multi-step syntheses.
