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+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+
Accessible (Haz class 3, 4, 5 or 8), International	$238.00+

Description

Potassium 2-bromo-2,2-difluoroacetate delivers a uniquely reactive trifluoromethylated synthon featuring a bromine atom adjacent to a stabilized carbanion. This bench-stable reagent facilitates efficient C–C bond formation in transition-metal-catalyzed coupling reactions and enables direct functionalization of electron-deficient substrates under mild conditions.

Application

Potassium 2-bromo-2,2-difluoroacetate serves as a versatile synthon for introducing the CF₂Br group into organic frameworks. It facilitates nucleophilic substitution reactions with amines, thiols, and stabilized carbon nucleophiles under mild conditions. The compound exhibits good bench stability and enables efficient access to fluorinated building blocks relevant to medicinal chemistry and agrochemical synthesis. Its reactivity profile supports straightforward functionalization in multi-step sequences.
