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

Tert-butyl 3-(trifluoromethyl)-1H-pyrazole-5-carboxylate is a bench-stable, moisture-tolerant heterocyclic building block featuring a trifluoromethyl group that imparts strong electron-withdrawing character. This pyrazole scaffold integrates readily into medicinal chemistry campaigns, where its solubility and stability streamline synthesis of bioactive compounds.

Application

Tert-butyl 3-(trifluoromethyl)-1H-pyrazole-5-carboxylate serves as a versatile building block in medicinal chemistry, enabling efficient access to trifluoromethylated pyrazole scaffolds. The tert-butyl ester group provides excellent bench stability and facilitates straightforward deprotection under mild acidic conditions. Its compatibility with standard coupling reactions and tolerance to diverse functional groups make it ideal for constructing complex heterocyclic architectures in API development.
