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-Bromo-3-methylpyrazolo[1,5-a]pyrimidine is a heterocyclic scaffold featuring a bromine atom at the 6-position and a methyl group at the 3-position, enabling direct functionalization in cross-coupling reactions. The electron-deficient pyrazolo[1,5-a]pyrimidine core enhances reactivity in transition-metal-catalyzed transformations, while the substituents provide steric and electronic tuning for synthetic applications. This compound serves as a key building block in medicinal chemistry and materials science.

Application

6-Bromo-3-methylpyrazolo[1,5-a]pyrimidine serves as a versatile building block in heterocyclic synthesis, enabling efficient access to pyrazolopyrimidine-based scaffolds. The bromine substituent facilitates palladium-catalyzed cross-coupling reactions, while the methyl group enhances solubility and modulates electronic properties. Its stability under standard reaction conditions and compatibility with diverse functional groups make it ideal for medicinal chemistry applications and the construction of bioactive molecules.
