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

2-Bromo-1,3-dichloro-5-fluorobenzene features a highly functionalized aromatic core with halogens at strategic positions, enabling direct coupling in cross-coupling reactions. This electron-deficient scaffold facilitates efficient Pd-catalyzed transformations, offering reliable access to complex fluorinated building blocks in medicinal chemistry and materials synthesis.

Application

2-Bromo-1,3-dichloro-5-fluorobenzene serves as a valuable building block in medicinal chemistry and agrochemical synthesis, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal halogen reactivity. The bromine center facilitates selective functionalization under standard Suzuki, Stille, or Negishi conditions, while the chlorine and fluorine substituents enhance metabolic stability and modulate electronic properties. Its bench-stable crystalline form simplifies handling and purification, making it well-suited for multi-step synthetic sequences.
