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

4-Bromo-5-methylpicolinaldehyde features a brominated pyridine core with a methyl substituent and aldehyde functionality, enabling direct incorporation into cross-coupling reactions. The electron-deficient heteroaryl ring facilitates palladium-catalyzed transformations, while the aldehyde group offers downstream derivatization potential. This bench-stable reagent streamlines access to complex nitrogen-containing scaffolds in medicinal chemistry and materials synthesis.

Application

4-Bromo-5-methylpicolinaldehyde serves as a versatile building block in medicinal chemistry and cross-coupling synthesis. Its aldehyde functionality enables direct incorporation into imines, oximes, and reductive amination workflows, while the bromine atom facilitates palladium-catalyzed coupling reactions. The methyl group enhances lipophilicity and provides a handle for further functionalization. This compound exhibits good bench stability and is compatible with standard reaction conditions, making it suitable for iterative synthetic sequences in API development.
