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

5-Bromo-2-chloroisonicotinaldehyde features a highly reactive aldehyde group flanked by bromo and chloro substituents at the 5- and 2-positions of the pyridine ring. This electron-deficient scaffold enables direct incorporation into cross-coupling reactions, offering precise control over regiochemistry in synthetic sequences. The compound demonstrates stability under standard handling conditions and serves as a key building block for functionalized heterocycles.

Application

5-Bromo-2-chloroisonicotinaldehyde serves as a versatile building block in medicinal chemistry, enabling direct incorporation of halogenated pyridine motifs into target molecules. Its aldehyde functionality facilitates nucleophilic addition and condensation reactions, while the ortho-halogen substituents support palladium-catalyzed cross-coupling transformations. The compound exhibits good bench stability and is compatible with standard protecting group strategies, making it well-suited for modular synthesis of functionalized heterocycles and API intermediates.
