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

2-Bromo-5-fluoro-4-methylpyrimidine features a strategically positioned bromine and fluorine substitution pattern that enables selective cross-coupling reactions. The methyl group enhances solubility and electronic modulation, while the halogen framework supports efficient palladium-catalyzed transformations. This pyrimidine derivative serves as a key building block in medicinal chemistry and agrochemical synthesis.

Application

2-Bromo-5-fluoro-4-methylpyrimidine serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions due to its well-defined halogen reactivity. The bromo group facilitates efficient C–C bond formation, while the fluorine and methyl substituents offer predictable electronic tuning and steric control. Its bench-stable crystalline form simplifies handling and purification, making it ideal for constructing heterocyclic scaffolds in API development.
