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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

This phosphonium salt features a methoxy-substituted alkyl chain terminating in a triphenylphosphonium cation, delivering enhanced solubility and stability under standard bench conditions. The electron-deficient phosphorus center enables efficient Wittig-type transformations and facilitates targeted delivery in bioconjugation workflows.

Application

(5-Methoxy-5-oxopentyl)triphenylphosphonium bromide serves as a versatile phosphonium salt for the synthesis of α,β-unsaturated carbonyl compounds via Wittig-type reactions. The methoxy and oxo groups enable selective functionalization and enhanced stability compared to analogous reagents. Its bench-stable solid form facilitates handling and purification, making it suitable for iterative synthesis workflows in complex molecule construction.
