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-Bromo-4-cyclopropylpyrimidine is a bench-stable heterocyclic building block featuring a bromine substituent at the 5-position and a cyclopropyl group at the 4-position. This combination enables efficient cross-coupling reactions, facilitating the construction of complex pyrimidine architectures in medicinal chemistry and materials science applications.

Application

5-Bromo-4-cyclopropylpyrimidine serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions due to its well-established reactivity at the bromine site. The cyclopropyl group provides steric and electronic modulation, enhancing metabolic stability and modulating physicochemical properties. Its bench-stable nature and compatibility with standard coupling conditions make it ideal for constructing complex heterocyclic scaffolds in API development.
