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

Dibenzo[b,e][1,4]dioxin features a rigid, planar polycyclic structure with two oxygen-bridged benzene rings, conferring high thermal stability and low solubility in aqueous media. This fused architecture imparts strong electron delocalization, making it a valuable scaffold in materials science and as a reference compound in environmental monitoring due to its structural persistence.

Application

Dibenzo[b,e][1,4]dioxin serves as a stable, rigid bicyclic scaffold in medicinal chemistry and materials science. Its fused aromatic system exhibits excellent bench stability and tolerates a range of functional groups, enabling its use in constructing bioactive heterocycles and advanced organic semiconductors. The core structure facilitates selective derivatization at the 2-, 3-, 6-, and 7-positions via standard coupling reactions, offering predictable regioselectivity for modular synthesis.
