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

1-(2,2-Difluoroethyl)-1H-pyrazol-4-amine features a pyrazole core bearing a primary amine at C4 and a difluoroethyl substituent at N1. This electron-deficient scaffold integrates readily into medicinal chemistry campaigns, offering enhanced metabolic stability and improved membrane permeability due to the fluorinated side chain.

Application

1-(2,2-Difluoroethyl)-1H-pyrazol-4-amine serves as a versatile building block in medicinal chemistry, enabling the construction of fluorinated heterocyclic scaffolds. The difluoroethyl side chain enhances metabolic stability and modulates lipophilicity, while the pyrazole amine moiety facilitates coupling reactions and hydrogen bonding interactions. Its bench-stable nature and compatibility with standard synthetic protocols make it well-suited for iterative library synthesis and API development.
