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

4-(Trifluoromethyl)benzenesulfonyl chloride may be used to synthesize -arylated thiophenes and 2,5-diarylated pyrrolevia palladium catalyzed desulfitative arylation of thiophenes and pyrroles, respectively.4-(Trifluoromethyl)benzenesulfonyl chloride and N-vinylpyrrolidinone in acetonitrile can undergo photo-irradiation with visible light in the presence of Ir(ppy)2(dtbbpy)PF6 ([4,4-bis(1,1-dimethylethyl)-2,2-bipyridine-N1,N1]bis[2-(2-pyridinyl-N)phenyl-C]iridium(III)hexafluorophosphate) and disodium phosphate to give the corresponding E-vinyl sulfone.

Application

4-(Trifluoromethyl)benzene-1-sulfonyl chloride serves as a robust sulfonylating agent for the efficient installation of sulfonamide groups under mild conditions. Its trifluoromethyl substituent enhances electrophilicity and imparts favorable lipophilic character, enabling high-yielding reactions with amines and alcohols. The reagent exhibits excellent bench stability and facilitates straightforward purification, making it ideal for constructing bioactive sulfonamide scaffolds in medicinal chemistry and process development workflows.
