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

Pyrazolo[1,5-a]pyrimidine-3-carbonitrile delivers a rigid, electron-deficient heterocyclic scaffold ideal for medicinal chemistry and materials science. This nitrogen-rich core integrates seamlessly into kinase inhibitors and organic semiconductors, offering enhanced stability and tunable electronic properties through functionalization at the carbonitrile group.

Application

Pyrazolo[1,5-a]pyrimidine-3-carbonitrile serves as a versatile heterocyclic building block in medicinal chemistry, enabling efficient construction of kinase inhibitors and other bioactive scaffolds. Its nitrile group provides high functional group tolerance and facilitates downstream transformations such as amidation or hydrolysis. The rigid, electron-deficient core enhances binding affinity in target-directed synthesis and supports robust performance in standard cross-coupling reactions.
