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

Quinazoline-2,4-diamine serves as a core scaffold in medicinal chemistry, offering a rigid, electron-rich platform for targeted drug design. This heterocyclic diamine integrates readily into kinase inhibitors and bioactive molecules, leveraging its ability to form key hydrogen bonds within protein binding pockets. Its bench-stable nature supports reliable use in synthetic workflows and structure-activity studies.

Application

Quinazoline-2,4-diamine serves as a key heterocyclic building block in medicinal chemistry, enabling the synthesis of kinase inhibitors and other bioactive scaffolds. Its two adjacent amine groups offer high reactivity for diverse functionalization—particularly in amidation, alkylation, and coupling reactions—facilitating rapid diversification. The compound exhibits good bench stability and is readily purified by recrystallization, making it well-suited for iterative library synthesis and process-scale applications.
