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

Isobutyl methanesulfonate serves as a robust alkylating agent in synthetic organic chemistry, offering high reactivity with nucleophiles under mild conditions. The molecule features a sterically hindered isobutyl group paired with a stable methanesulfonate leaving group, enabling selective transformations. This combination ensures efficient coupling reactions with minimal side products, making it well-suited for applications in pharmaceutical intermediates and complex molecule synthesis.

Application

Isobutyl methanesulfonate serves as a reliable alkylating agent in synthetic organic chemistry, enabling efficient SN2 reactions with nucleophiles under mild conditions. Its bench-stable nature and low hydrolytic sensitivity facilitate straightforward handling and purification. The methanesulfonyl group provides excellent leaving group capability, making it particularly useful for constructing C–C and C–heteroatom bonds in complex molecule synthesis, including intermediates for pharmaceutical scaffolds and functionalized building blocks.
