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

Excitable by blue LEDs, this photocatalyst was reported by the Nicewicz laboratory for catalysis of O-aryl carbamothioates to S-aryl carbamothioates at ambient temperatures, an improvement from the elevated reaction temperatures traditionally needed in the Newman-Kwart rearrangment or palladium catalysis. Effective for scale-up or flow chemistry, this triarylpyrylium salt provides convenient access to thiophenols from phenols.
