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-Chloro-2-fluoro-4-vinylbenzene features a vinyl group conjugated to an electron-deficient aryl ring bearing ortho-fluoro and para-chloro substituents. This configuration enables efficient copolymerization in functional materials synthesis, where the vinyl moiety integrates readily into polymer backbones under standard conditions. The fluorine and chlorine atoms enhance stability and influence electronic properties in downstream applications.

Application

1-Chloro-2-fluoro-4-vinylbenzene serves as a versatile building block in cross-coupling and heterocyclic synthesis, enabling efficient access to functionalized aryl scaffolds. The vinyl group facilitates Heck and Suzuki-Miyaura reactions, while the ortho-fluoro and para-chloro substituents provide orthogonal reactivity for sequential transformations. Bench-stable and compatible with standard purification methods, it functions reliably in the construction of complex pharmaceutical intermediates and advanced materials.
