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

Ethyl 5-chloropyrazolo[1,5-a]pyrimidine-2-carboxylate features a chlorinated pyrazolopyrimidine core that enables direct functionalization in heterocyclic synthesis. This bench-stable, moisture-tolerant building block integrates readily into medicinal chemistry campaigns targeting kinase inhibitors and antiviral agents.

Application

Ethyl 5-chloropyrazolo[1,5-a]pyrimidine-2-carboxylate serves as a versatile building block for constructing biologically relevant heterocyclic scaffolds. The chloro group at the C5 position enables facile nucleophilic substitution, while the pyrazolo[1,5-a]pyrimidine core provides a rigid, electron-deficient platform suitable for further functionalization. Its bench-stable nature and compatibility with standard coupling reactions facilitate efficient synthesis of substituted derivatives used in medicinal chemistry and agrochemical research.
