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-Chloro-5-fluoropyrimidin-4-amine features a dual halogenated pyrimidine core, combining chlorine and fluorine substituents at electron-deficient positions. This configuration enhances reactivity in cross-coupling processes while maintaining stability under standard conditions. The primary amine group enables direct incorporation into pharmaceutical scaffolds and functionalized heterocycles.

Application

6-Chloro-5-fluoropyrimidin-4-amine serves as a versatile building block in medicinal chemistry, enabling efficient construction of pyrimidine-based scaffolds. Its orthogonal halogen functionality facilitates palladium-catalyzed cross-coupling reactions, while the primary amine supports derivatization via acylation or alkylation. The compound exhibits good bench stability and is compatible with standard purification protocols, making it well-suited for iterative synthesis campaigns in API development.
