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

N-Butyl disulfide features a linear alkyl chain flanked by two sulfur atoms, delivering enhanced stability and solubility in nonpolar solvents. This compound serves as a robust sulfur transfer agent in synthetic transformations, enabling efficient incorporation of thiol functionalities under mild conditions.

Application

N-Butyl disulfide serves as a stable, bench-friendly thiol equivalent in synthetic workflows, enabling controlled disulfide formation and reduction. It functions as a versatile building block for sulfur-containing heterocycles and peptide-cysteine analogs, offering excellent functional group tolerance and ease of purification. Its low volatility and thermal stability facilitate reliable use in air-sensitive transformations and scale-up applications.
