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 bench-stable phosphonium salt features a benzyl-protected methylene group flanked by triphenylphosphine, enabling efficient Wittig-type olefination under mild conditions. The chloride counterion enhances solubility in polar aprotic solvents, facilitating smooth reaction initiation and consistent yields in synthetic sequences requiring stable, handleable ylide precursors.

Application

((Benzyloxy)methyl)triphenylphosphonium chloride serves as a reliable Wittig reagent precursor, enabling efficient synthesis of allylic and homoallylic alcohols via stabilized ylide formation. Its bench-stable solid form facilitates handling and purification, while the benzyloxy group provides orthogonal protection compatibility in complex molecule assembly. Functions effectively in standard carbonyl olefination protocols with high stereoselectivity and minimal side reactions.
