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)triphenylsilane features a brominated aryl group attached to a triphenylsilyl moiety, enabling robust cross-coupling transformations. This bench-stable reagent facilitates efficient palladium-catalyzed reactions under standard conditions, delivering high yields in the construction of biaryl architectures with minimal side-product formation.

Application

(4-Bromophenyl)triphenylsilane serves as a stable, bench-ready arylsilane building block for palladium-catalyzed cross-coupling reactions. Its bromo group enables efficient Suzuki-Miyaura coupling with boronic acids, while the triphenylsilyl moiety provides steric protection and enhances solubility. The compound exhibits excellent functional group tolerance and facilitates clean, high-yielding transformations in complex molecule synthesis.
