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-methylthieno[3,2-d]pyrimidine is a bench-stable heterocyclic scaffold featuring a chlorine substituent at the 4-position and a methyl group at the 7-position. This electron-deficient core integrates readily into kinase inhibitor designs and serves as a key building block in medicinal chemistry for targeted therapeutics.

Application

4-Chloro-7-methylthieno[3,2-d]pyrimidine serves as a versatile heterocyclic building block for medicinal chemistry and agrochemical synthesis. Its chloro group enables palladium-catalyzed cross-coupling reactions, while the methylthienopyrimidine core provides structural rigidity and favorable electronic properties. The compound exhibits bench stability and facilitates efficient functionalization in standard synthetic workflows, making it well-suited for constructing complex scaffolds in drug discovery programs.
