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

This pyrrolopyrimidine scaffold features two chlorine substituents at the 2,4-positions, enhancing electron deficiency and enabling selective coupling in cross-coupling reactions. The dihydro structure provides a stable, bench-ready platform for synthesizing kinase inhibitors and nucleoside analogs.

Application

2,4-Dichloro-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidine serves as a versatile building block for purine-based heterocycles, enabling efficient construction of biologically relevant scaffolds. Its dichloro substitution pattern facilitates selective nucleophilic displacement reactions, offering high functional group tolerance and bench stability. The compound functions effectively in Pd-catalyzed cross-coupling and amine displacement protocols, supporting scalable synthesis of kinase inhibitors and other medicinal chemistry targets.
