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 2-chloro-4-fluoropyridine-3-carboxylate is a bench-stable, moisture-tolerant heterocyclic building block featuring orthogonal reactivity. The electron-deficient pyridine core enables selective functionalization at the 2-chloro and 4-fluoro positions, while the ester group facilitates downstream derivatization. This compound integrates efficiently into synthetic routes for pharmaceutical intermediates and agrochemical scaffolds.

Application

Methyl 2-chloro-4-fluoropyridine-3-carboxylate serves as a versatile building block in medicinal chemistry, enabling efficient construction of pyridine-based scaffolds. Its orthogonal reactivity—where the chloro group undergoes palladium-catalyzed cross-coupling while the fluorine facilitates nucleophilic substitution—supports modular synthesis of complex heterocycles. The ester functionality offers stability and ease of purification, making it well-suited for multi-step sequences in API development.
