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.

Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

2-Chlorothieno[3,2-d]pyrimidine features a fused thienopyrimidine core with a chlorine substituent at the 2-position, delivering enhanced electron deficiency and improved metabolic stability. This scaffold integrates readily into kinase inhibitors and bioactive heterocycles, offering high reactivity in cross-coupling and nucleophilic substitution reactions under standard conditions.

Application

2-Chlorothieno[3,2-d]pyrimidine serves as a versatile heterocyclic building block for medicinal chemistry and materials science, enabling efficient construction of kinase inhibitors and functionalized π-conjugated systems. Its chlorine substituent facilitates palladium-catalyzed cross-coupling reactions, while the fused thienopyrimidine core provides enhanced metabolic stability and planar rigidity. The compound exhibits excellent bench stability and compatibility with diverse reaction conditions, making it a practical scaffold for high-throughput synthesis and API development.
