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

Potassium (4-bromophenyl)trifluoroborate delivers a stable, bench-ready boronate handle for Suzuki-Miyaura cross-coupling reactions. This moisture-tolerant reagent integrates seamlessly into synthetic workflows, enabling efficient C–C bond formation under mild conditions. The para-brominated aryl trifluoroborate combines high functional group compatibility with predictable reactivity, streamlining access to complex biaryl architectures in pharmaceutical and materials synthesis.

Application

Potassium (4-bromophenyl)trifluoroborate serves as a stable, bench-ready boron reagent for palladium-catalyzed cross-coupling reactions. It facilitates efficient Suzuki-Miyaura coupling with aryl and heteroaryl halides, offering excellent functional group tolerance and reliable yields. The trifluoroborate moiety enhances stability and solubility compared to traditional boronic acids, enabling straightforward handling and purification in synthetic workflows.
