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

2,4,5-Trichloroquinazoline features a highly electron-deficient quinazoline core with three strategically positioned chlorine substituents. This configuration enhances reactivity in nucleophilic substitution processes and provides stability under standard bench conditions. The molecule serves as a key scaffold for synthesizing bioactive heterocycles in medicinal chemistry and materials science applications.

Application

2,4,5-Trichloroquinazoline serves as a versatile building block in medicinal chemistry, enabling direct functionalization at multiple positions due to its electron-deficient heterocyclic core. The trichloro substitution pattern facilitates nucleophilic aromatic substitution (SNAr) under mild conditions, allowing efficient introduction of diverse amine and thiol derivatives. Its bench-stable nature and compatibility with common reaction protocols make it a practical choice for synthesizing kinase inhibitor scaffolds and other bioactive heterocycles.
