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

3,4-Dichloropyridine serves as a pivotal heterocyclic scaffold in medicinal chemistry and agrochemical synthesis. The ortho-dichloro substitution pattern imparts enhanced electrophilicity at the ring carbon positions, facilitating nucleophilic aromatic substitution reactions. This compound exhibits robust stability under standard conditions and integrates readily into complex molecular architectures via coupling processes.

Application

3,4-Dichloropyridine serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient functionalization at the 3- and 4-positions via palladium-catalyzed cross-coupling reactions. Its dual chloro substituents offer orthogonal reactivity for sequential transformations, while the pyridine core provides excellent stability and compatibility with diverse reaction conditions. This compound functions effectively in C–H activation, nucleophilic substitution, and heterocycle elaboration workflows, facilitating rapid access to complex scaffolds used in drug discovery and materials science.
