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 dipropionic acid derivative features a propane-2,2-diylbis(sulfanediyl) linker that delivers enhanced solubility and stability. The molecule integrates two carboxylic acid groups flanking a central sulfide bridge, enabling efficient conjugation in bioorthogonal labeling and polymer functionalization workflows under standard conditions.

Application

3,3'-(Propane-2,2-diylbis(sulfanediyl))dipropionic acid serves as a versatile bifunctional building block featuring two terminal carboxylic acid groups flanking a central dithiolane scaffold. It facilitates the construction of disulfide-linked architectures and heterocyclic systems through standard coupling and cyclization protocols. The molecule exhibits good bench stability and functional group tolerance, enabling reliable use in peptide conjugation, macrocyclization, and the synthesis of thiol-based pharmaceutical intermediates.
