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+
Inaccessible (Haz class 6.1 or 9), International	$108.00+
Accessible (Haz class 3, 4, 5 or 8), International	$238.00+

Description

4-Chloro-3,5-difluoroaniline delivers a trifunctional aromatic scaffold with orthogonal reactivity. The para-chloro and ortho-fluoro substituents enable selective coupling under mild conditions. This electron-deficient aniline integrates readily into pharmaceutical intermediates and agrochemicals, offering enhanced metabolic stability and controlled reactivity in multi-step syntheses.

Application

4-Chloro-3,5-difluoroaniline serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient construction of heterocyclic scaffolds via standard coupling reactions. Its electron-deficient aromatic ring enhances reactivity in nucleophilic substitution and palladium-catalyzed cross-coupling processes, while the amine functionality provides a reliable handle for derivatization. Bench-stable and readily purified, it facilitates scalable synthesis of complex targets with high functional group tolerance.
