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 cyclopenta[b]pyridine derivative features a fused bicyclic core with strategically positioned chlorine atoms at the 2 and 4 positions, enhancing electron deficiency and enabling selective reactivity in cross-coupling and heterocyclic synthesis. The dihydro structure provides synthetic accessibility while maintaining stability under standard conditions.

Application

2,4-Dichloro-6,7-dihydro-5H-cyclopenta[b]pyridine serves as a versatile building block for heterocyclic synthesis, enabling efficient access to substituted pyridine scaffolds via palladium-catalyzed cross-coupling reactions. Its dichloro substitution pattern facilitates sequential functionalization, while the saturated cyclopenta ring offers enhanced stability and predictable reactivity in standard synthetic workflows. The compound exhibits excellent bench stability and is readily purified by column chromatography, making it well-suited for medicinal chemistry and process development applications.
