    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

Butyltriphenylphosphonium bromide serves as a stable, bench-ready phosphonium salt for Wittig-type olefination reactions. Featuring a bulky triphenylphosphonium head and a butyl tether, it delivers high chemoselectivity in ylide formation under mild conditions. The bromide counterion ensures efficient activation without requiring anhydrous handling. This reagent enables reliable C=C bond construction in complex molecule synthesis.

Application

Butyltriphenylphosphonium bromide serves as a reliable precursor for Wittig reagents, enabling efficient olefination reactions with aldehydes and ketones under mild conditions. The triphenylphosphonium salt exhibits excellent bench stability and facilitates clean elimination to generate phosphine oxide byproducts, simplifying purification. Its functional group tolerance supports use in complex molecule synthesis, making it a practical choice for constructing carbon–carbon double bonds in pharmaceutical and natural product workflows.
