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

4-Bromo-2-fluorotoluene is a fluorinated aryl halide featuring complementary electrophilic handles at the para-bromo and ortho-fluoro positions. This strategic substitution pattern enables selective cross-coupling reactions in palladium-catalyzed processes, offering enhanced regiocontrol for complex molecule assembly. The compound exhibits excellent stability under standard bench conditions and integrates seamlessly into synthetic workflows requiring precise functional group placement.

Application

4-Bromo-2-fluorotoluene serves as a versatile building block in synthetic organic chemistry, enabling palladium-catalyzed cross-coupling reactions such as Suzuki, Stille, and Negishi couplings. Its ortho-fluoro substitution enhances regioselectivity in electrophilic aromatic substitution, while the bromine handle provides high reactivity in transition metal-mediated transformations. The compound exhibits excellent bench stability and is compatible with diverse functional groups, facilitating efficient synthesis of substituted arenes and heterocyclic scaffolds relevant to pharmaceutical development.
