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-Bromo-4-chloro-2-methylquinazoline features a sterically accessible quinazoline core with complementary halogenation and methyl substitution. This configuration enables direct functionalization in cross-coupling reactions, delivering diverse heterocyclic architectures under standard conditions. The electron-deficient ring system enhances reactivity in Pd-catalyzed transformations while maintaining bench-stable handling properties.

Application

6-Bromo-4-chloro-2-methylquinazoline serves as a versatile building block for the synthesis of kinase inhibitors and other bioactive heterocycles. Its complementary halogenation pattern enables palladium-catalyzed cross-coupling reactions with high efficiency, while the methyl group provides a site for further functionalization. The compound exhibits excellent bench stability and facilitates straightforward purification, making it well-suited for both medicinal chemistry and process-scale applications.
