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-ethylpyrimidine serves as a key heterocyclic scaffold for medicinal chemistry and materials synthesis. The bromine at the 5-position enables efficient cross-coupling reactions, while the ethyl group at the 4-position imparts favorable steric and electronic properties. This compound offers enhanced stability and solubility in organic media, facilitating its integration into complex molecular architectures under standard conditions.

Application

5-Bromo-4-ethylpyrimidine serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions for the construction of biologically relevant pyrimidine scaffolds. The bromine at C5 provides a reliable site for Suzuki, Stille, and Negishi couplings, while the ethyl group at C4 enhances solubility and modulates electronic properties. Bench-stable and readily purified by distillation or flash chromatography, it functions effectively in multi-step syntheses of kinase inhibitors and nucleoside analogs.
