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

Diphenylethyl)phosphine is a versatile reagent used in a number of scientific research applications. It can be used as a catalyst in organic synthesis, as a ligand in coordination chemistry, and as a reagent in biochemistry and drug discovery. In addition, it has been used as a cross-linking agent in the synthesis of polymers and as a fluorescent probe in imaging studies.

Application

Diphenyl sulfoxide serves as a stable, bench-ready chiral auxiliary and oxidation state modulator in synthetic organic chemistry. It functions as a versatile precursor for sulfonium salt formation and enables stereoselective transformations via directed metalation or electrophilic capture. Its robustness under standard reaction conditions and compatibility with diverse functional groups make it a practical choice for complex molecule assembly and heterocyclic scaffold construction.
