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

2,4-Difluoropyrimidine serves as a key heterocyclic scaffold in medicinal chemistry, offering enhanced metabolic stability and improved membrane permeability. The strategically positioned fluorine atoms enable favorable electronic effects and facilitate C–H functionalization. This electron-deficient pyrimidine integrates efficiently into kinase inhibitors and antiviral agents, providing a robust platform for target-specific drug design under standard bench conditions.

Application

2,4-Difluoropyrimidine serves as a versatile building block in medicinal chemistry, enabling efficient late-stage functionalization via nucleophilic substitution at the C2 or C4 position. Its high reactivity profile facilitates the construction of diverse heterocyclic scaffolds, particularly in kinase inhibitor and antiviral agent development. The molecule exhibits excellent bench stability and compatibility with common reaction conditions, simplifying purification and scale-up. Functions as a key motif in API synthesis due to its favorable metabolic stability and ability to modulate target binding affinity.
