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

4-Chloro-5-fluoro-2-methoxypyrimidine features a pyrimidine core functionalized with chlorine, fluorine, and methoxy groups at strategic positions. This electron-deficient heterocycle integrates readily into cross-coupling reactions and serves as a key intermediate in the synthesis of pharmaceuticals and agrochemicals requiring precise substitution patterns.

Application

4-Chloro-5-fluoro-2-methoxypyrimidine serves as a versatile building block in medicinal chemistry, enabling efficient construction of pyrimidine-based scaffolds. Its orthogonal halogen and methoxy functionalities facilitate sequential cross-coupling reactions and nucleophilic substitutions under mild conditions. The compound exhibits excellent bench stability and facilitates rapid diversification in the synthesis of kinase inhibitors and antiviral agents.
