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.

Type	HazMat Fee

Description

Ethyl 4-chlorothieno[2,3-d]pyrimidine-6-carboxylate features a chlorinated thienopyrimidine core that enables direct functionalization in medicinal chemistry. This electron-deficient heterocycle integrates readily into kinase inhibitor scaffolds and serves as a key intermediate for bioactive purine analogs under standard conditions.

Application

Ethyl 4-chlorothieno[2,3-d]pyrimidine-6-carboxylate serves as a versatile building block for the synthesis of thienopyrimidine-based heterocycles. The chloro group at the 4-position enables palladium-catalyzed cross-coupling reactions, while the ester functionality supports subsequent transformations into carboxylic acids or amides. Its bench-stable nature and compatibility with standard synthetic protocols make it well-suited for medicinal chemistry campaigns targeting kinase inhibitors and other bioactive scaffolds.
