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

Methyl 4,5-dichloropicolinate is a bench-stable, moisture-tolerant heterocyclic ester featuring two adjacent chlorine substituents at the 4- and 5-positions of the picolinate ring. This electron-deficient scaffold integrates readily into synthetic sequences requiring halogenated building blocks. The methyl ester functionality enables straightforward derivatization, while the ortho-chlorine pattern enhances reactivity in cross-coupling processes.

Application

Methyl 4,5-dichloropicolinate serves as a versatile building block in synthetic organic chemistry, enabling efficient access to substituted pyridine scaffolds. Its dual chlorine substituents at the 4- and 5-positions provide enhanced electrophilicity for nucleophilic aromatic substitution, while the methyl ester facilitates downstream functionalization via hydrolysis or coupling reactions. The compound exhibits excellent bench stability and compatibility with standard reaction conditions, making it well-suited for medicinal chemistry campaigns and process development workflows requiring reliable heterocyclic core construction.
