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

2,4-Dibromo-3-methylpyridine features a pyridine core with bromine substituents at the 2 and 4 positions and a methyl group at the 3 position, delivering enhanced reactivity for cross-coupling applications. The electron-deficient aromatic ring enables efficient palladium-catalyzed transformations, while the sterically accessible methyl moiety provides a handle for further functionalization. This bench-stable compound serves as a key building block in the synthesis of bioactive heterocycles and advanced materials.

Application

2,4-Dibromo-3-methylpyridine serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling palladium-catalyzed cross-coupling reactions due to its well-defined halogen reactivity. The methyl group enhances regioselectivity in electrophilic substitutions, while the dibromo substitution pattern facilitates sequential functionalization. Its bench-stable nature and compatibility with standard purification protocols make it ideal for multi-step synthetic sequences requiring precise heterocyclic scaffolding.
