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

(4-Bromophenyl)dimethylphosphine oxide features a brominated aryl group coupled to a phosphine oxide moiety, delivering enhanced electronic and steric properties. This bench-stable compound integrates readily into cross-coupling protocols and serves as a tailored ligand scaffold for transition metal catalysis.

Application

(4-Bromophenyl)dimethylphosphine oxide serves as a stable, bench-ready phosphine derivative enabling palladium-catalyzed cross-coupling reactions. Its bromo substituent facilitates further functionalization via Negishi, Suzuki-Miyaura, or Stille coupling protocols. The dimethylphosphine oxide group provides excellent functional group tolerance and ease of purification, making it a practical building block for the synthesis of biaryl scaffolds and complex pharmaceutical intermediates.
