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-Bromo-4,5-dimethylpyridine is a bench-stable, electron-deficient heterocycle featuring two methyl groups at the 4- and 5-positions. This substitution pattern enhances regioselectivity in cross-coupling reactions, enabling efficient construction of complex pyridyl architectures. The bromine atom serves as a reliable handle for palladium-catalyzed transformations, facilitating direct functionalization in medicinal chemistry and materials synthesis.

Application

2-Bromo-4,5-dimethylpyridine serves as a versatile building block in medicinal chemistry and materials science, enabling palladium-catalyzed cross-coupling reactions such as Suzuki-Miyaura and Buchwald-Hartwig aminations. Its electron-rich pyridine core and bromine substituent offer favorable reactivity for C–C and C–N bond formation, while the methyl groups enhance stability and solubility. The compound exhibits robust bench stability and is readily purified by flash chromatography or recrystallization, facilitating integration into multi-step syntheses of heterocyclic scaffolds and functionalized aryl derivatives.
