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-Chloro-5-nitroisonicotinic acid features a chlorine atom at the 2-position and a nitro group at the 5-position on the pyridine ring, delivering high electron deficiency for coupling reactions. This bench-stable, moisture-tolerant derivative integrates readily into pharmaceutical intermediates and functional materials, enabling efficient access to complex heterocyclic architectures under standard conditions.

Application

2-Chloro-5-nitroisonicotinic acid serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient access to substituted pyridine scaffolds. Its orthogonal functional groups—chlorine at C-2 and nitro at C-5—facilitate diverse downstream transformations, including palladium-catalyzed cross-coupling and selective reduction sequences. The compound exhibits good bench stability and is amenable to standard purification methods, supporting reliable integration into multi-step synthetic workflows.
