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

6,7-Dimethoxyquinazolin-4-amine delivers a potent heterocyclic scaffold with enhanced solubility and metabolic stability. The dimethoxy substitution pattern at the 6,7-positions confers favorable electronic properties for kinase inhibition, while the amine functionality enables direct coupling in medicinal chemistry campaigns. This bench-stable compound integrates efficiently into targeted drug discovery pipelines.

Application

6,7-Dimethoxyquinazolin-4-amine serves as a versatile building block in medicinal chemistry, enabling efficient access to quinazoline-based kinase inhibitors and bioactive heterocycles. Its dimethoxy substitution pattern enhances solubility and modulates electronic properties, while the primary amine facilitates straightforward derivatization via amidation, alkylation, or coupling reactions. Bench-stable and readily purified by recrystallization, it functions reliably in standard synthetic workflows for API development and scaffold diversification.
