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

This 2,2-dimethyl-4,7-dihydro-1,3-dioxepine features a stable, moisture-tolerant dioxepine ring system that integrates readily into complex molecular architectures. Its electron-rich heterocyclic core enables efficient coupling in synthetic sequences, particularly in the construction of oxygen-containing macrocycles and biologically relevant scaffolds under standard conditions.

Application

2,2-Dimethyl-4,7-dihydro-1,3-dioxepine serves as a stable, bench-accessible synthon for the construction of oxygen-containing heterocycles. Its electrophilic C4 position enables regioselective nucleophilic addition, facilitating the synthesis of functionalized dihydrofuran derivatives and complex carbohydrate analogs. The molecule exhibits excellent functional group tolerance and compatibility with standard coupling protocols, enabling efficient incorporation into diverse synthetic scaffolds.
