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

1-(2,4-Dichloropyridin-3-yl)ethanone features a pyridine ring bearing two chlorine substituents at the 2- and 4-positions, creating a highly electron-deficient heterocyclic core. This structure integrates a ketone group at the 3-position, enabling direct coupling in cross-coupling reactions or nucleophilic addition processes. The compound exhibits enhanced stability under standard bench conditions and serves as a key intermediate in the synthesis of bioactive molecules and functionalized pharmaceuticals.

Application

1-(2,4-Dichloropyridin-3-yl)ethanone serves as a versatile building block in medicinal chemistry, enabling efficient construction of pyridine-based scaffolds. Its electrophilic acyl group facilitates nucleophilic substitution and condensation reactions, particularly in the synthesis of heterocyclic compounds. The 2,4-dichloro substitution pattern provides enhanced reactivity and orthogonal functionalization potential, while the ketone functionality offers stability and compatibility with standard purification methods. This compound functions effectively in late-stage modifications and is well-suited for scalable synthetic processes.
