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

Dihydrothiophen-3(2H)-one 1,1-dioxide features a sulfonyl-stabilized heterocyclic core with enhanced solubility in polar solvents. This bench-stable scaffold integrates readily into synthetic sequences requiring electron-deficient, oxygen-tolerant building blocks. The sulfone moiety imparts high thermal resilience and facilitates downstream functionalization via nucleophilic substitution or transition-metal-catalyzed coupling.

Application

Dihydrothiophen-3(2H)-one 1,1-dioxide serves as a versatile sulfur-containing heterocyclic building block in medicinal chemistry and synthetic organic chemistry. Its sulfone functionality enhances metabolic stability and modulates electronic properties, while the enolizable carbonyl enables diverse transformations including nucleophilic additions and condensations. The compound exhibits good bench stability and facilitates efficient functionalization, making it valuable for constructing complex scaffolds in API development.
