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

Triphenyl(4-pyridylmethyl)phosphonium chloride features a pyridylmethyl-linked phosphonium center with enhanced solubility in polar solvents. This bench-stable cation integrates readily into catalytic systems and stabilizes reactive intermediates in organic synthesis, particularly in Wittig-type transformations and phase-transfer applications.

Application

Triphenyl(4-pyridylmethyl)phosphonium chloride serves as a versatile phase-transfer catalyst and precursor in nucleophilic substitution reactions. Its pyridylmethyl group enables stable coordination to metal ions and facilitates efficient transfer of anions across phase boundaries. The compound exhibits excellent bench stability, ease of handling, and compatibility with a broad range of functional groups, making it well-suited for synthetic workflows requiring mild, selective activation under ambient conditions.
