    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

6-Bromopyrazolo[1,5-a]pyrimidine serves as a pivotal heterocyclic scaffold for constructing bioactive molecules. This brominated pyrazolopyrimidine features a reactive site at the 6-position, enabling facile cross-coupling reactions. The electron-deficient core supports efficient functionalization in medicinal chemistry and materials science applications.

Application

6-Bromopyrazolo[1,5-a]pyrimidine serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions to install diverse aryl and heteroaryl substituents. Its bromine at the C6 position exhibits high reactivity in Suzuki, Stille, and Negishi couplings, with excellent functional group tolerance and bench stability. The pyrazolo[1,5-a]pyrimidine core provides a rigid, electron-deficient scaffold suitable for kinase inhibitor development and other bioactive molecule synthesis.
