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.

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

5,6-Dichlorobenzo[d][1,3]dioxole features a rigid, electron-deficient dioxole core flanked by chlorine substituents at the 5- and 6-positions. This structural motif imparts enhanced stability and facilitates selective coupling in transition metal-catalyzed reactions. The molecule serves as a key building block in the synthesis of advanced functional materials and bioactive heterocycles.

Application

5,6-Dichlorobenzo[d][1,3]dioxole serves as a versatile heterocyclic building block in medicinal chemistry and materials science. Its rigid, electron-deficient core facilitates coupling reactions with boronic acids and stannanes via palladium-catalyzed cross-coupling protocols. The dichloro substituents enable further functionalization through nucleophilic aromatic substitution, offering orthogonal access to diverse analogs. Bench-stable and readily purified by flash chromatography, it functions effectively in the synthesis of complex pharmaceutical scaffolds and optoelectronic intermediates.
