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

2,4-Dichloro-5-methylpyridine serves as a key heterocyclic building block in medicinal chemistry and agrochemical synthesis. The molecule features a pyridine core substituted with chlorine atoms at positions 2 and 4, and a methyl group at position 5, conferring enhanced stability and tailored electronic properties. This combination enables efficient coupling reactions and facilitates the construction of complex functionalized scaffolds under standard conditions.

Application

2,4-Dichloro-5-methylpyridine serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient late-stage functionalization via palladium-catalyzed cross-coupling reactions. The dichloro substitution pattern provides orthogonal reactivity for sequential derivatization, while the methyl group enhances metabolic stability and modulates electronic properties. Its bench-stable nature and compatibility with standard reaction conditions facilitate scalable synthesis of complex heterocyclic scaffolds.
