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

5,7-Dichloro-3-isopropylpyrazolo[1,5-a]pyrimidine features a sterically hindered isopropyl group flanking an electron-deficient pyrazolopyrimidine core, enhancing metabolic stability and enabling selective integration into kinase inhibitor scaffolds. This scaffold delivers robust reactivity under standard conditions for medicinal chemistry applications.

Application

5,7-Dichloro-3-isopropylpyrazolo[1,5-a]pyrimidine serves as a versatile building block in medicinal chemistry, enabling efficient construction of purine-like scaffolds. Its dichloro substitution pattern facilitates selective functionalization at C5 and C7, while the isopropyl group enhances solubility and modulates electronic properties. The scaffold exhibits excellent bench stability and compatibility with standard coupling reactions, supporting rapid diversification in kinase inhibitor and nucleoside analog development.
