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

5h,6h,7h-Cyclopenta[d]pyrimidin-2-amine is a heterocyclic scaffold featuring a fused cyclopentane ring fused to a pyrimidine core, offering a rigid, electron-rich platform for medicinal chemistry. This structure integrates seamlessly into kinase inhibitors and nucleoside analogs due to its ability to mimic purine bases while maintaining metabolic stability.

Application

5H,6H,7H-Cyclopenta[d]pyrimidin-2-amine serves as a core heterocyclic scaffold in medicinal chemistry, enabling the synthesis of purine analogs and kinase inhibitors. Its planar, electron-rich framework facilitates transition-metal-catalyzed coupling reactions and supports functionalization at multiple positions. The amine group provides a versatile handle for derivatization, while the fused ring system offers enhanced metabolic stability and favorable binding interactions in target-directed synthesis.
