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-2-fluoropyrimidine serves as a key heterocyclic building block for medicinal chemistry and agrochemical synthesis. This electron-deficient pyrimidine features orthogonal halogen substituents enabling sequential cross-coupling reactions. The fluorine at the 2-position enhances metabolic stability, while the bromine facilitates palladium-catalyzed functionalization. This combination enables efficient diversification of pharmaceutical scaffolds under standard conditions.

Application

5-Bromo-2-fluoropyrimidine serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal halogen reactivity. The bromine at C5 facilitates Suzuki, Stille, or Negishi coupling, while the fluorine at C2 allows for directed functionalization or modulation of electronic properties. This compound exhibits excellent bench stability, ease of handling, and compatibility with diverse reaction conditions, making it a reliable scaffold for constructing complex heterocyclic frameworks in drug discovery and process development workflows.
