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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

2-Bromo-4-chloropyridine-3-carbaldehyde features a pyridine core functionalized with bromo, chloro, and aldehyde groups at positions 2, 4, and 3, respectively. This electron-deficient heterocycle enables direct coupling in cross-coupling reactions and serves as a key intermediate for pharmaceuticals and agrochemicals. The aldehyde group provides a handle for further derivatization via condensation or reductive amination.

Application

2-Bromo-4-chloropyridine-3-carbaldehyde serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling direct incorporation of halogenated pyridine scaffolds into target molecules. Its aldehyde functionality facilitates nucleophilic additions, reductive aminations, and condensation reactions, while the bromo and chloro substituents support subsequent cross-coupling transformations. The compound exhibits good bench stability and is compatible with standard purification protocols, making it well-suited for multi-step synthetic sequences requiring functional group orthogonality and predictable reactivity.
