    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.

Description

1,4-Dibromo-2,3-difluorobenzene features a rigid aromatic core with complementary halogen substituents enabling precise cross-coupling reactions. The bromine atoms serve as effective coupling handles, while the fluorine groups enhance electronic modulation and metabolic stability in synthetic intermediates.

Application

1,4-Dibromo-2,3-difluorobenzene serves as a versatile building block in cross-coupling reactions, enabling the construction of complex fluorinated aromatic scaffolds. Its orthogonal halogen reactivity facilitates sequential Pd-catalyzed couplings, while the difluoro substitution enhances metabolic stability and modulates electronic properties. The compound exhibits excellent bench stability and is amenable to standard purification protocols, making it well-suited for iterative synthetic strategies in medicinal chemistry and materials science.
