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-7-nitroquinazoline features a fused bicyclic core with complementary electron-withdrawing groups at the 4-chloro and 7-nitro positions, enabling selective reactivity in cross-coupling and bioconjugation workflows. This bench-stable scaffold integrates readily into kinase inhibitor libraries and serves as a key intermediate for targeted covalent probe development under standard conditions.

Application

4-Chloro-7-nitroquinazoline serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions at the C4 position due to its activated halide. The electron-withdrawing nitro group at C7 enhances electrophilicity and facilitates nucleophilic substitution, while the quinazoline core provides a rigid scaffold for targeted drug discovery. Its bench-stable nature and compatibility with standard reaction conditions make it suitable for iterative synthesis of kinase inhibitors and other heterocyclic APIs.
