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

3-Bromo-4,5-dimethylpyridine features a bromine atom at the 3-position and methyl groups at the 4- and 5-positions of the pyridine ring, delivering enhanced reactivity in cross-coupling processes. The electron-rich aromatic core supports efficient palladium-catalyzed transformations, while the steric profile from adjacent methyl substituents improves selectivity in complex synthetic sequences. This bench-stable compound integrates seamlessly into medicinal chemistry and materials synthesis workflows.

Application

3-Bromo-4,5-dimethylpyridine serves as a versatile building block in medicinal chemistry and catalytic cross-coupling reactions. The bromine substituent enables reliable Suzuki, Stille, and Negishi couplings, while the methyl groups enhance solubility and influence electronic properties. Its bench-stable nature and compatibility with standard reaction conditions facilitate efficient synthesis of functionalized heterocycles and advanced intermediates for API development.
