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

2,5-Dibromo-4-methyl-3-nitropyridine features a sterically hindered pyridine core bearing two bromine atoms at positions 2 and 5, a methyl group at C4, and a nitro group at C3. This electron-deficient heterocycle serves as a key building block for constructing complex nitrogen-containing scaffolds in medicinal chemistry and materials science. The molecule exhibits enhanced stability under standard handling conditions and integrates readily into cross-coupling reactions.

Application

2,5-Dibromo-4-methyl-3-nitropyridine serves as a versatile building block in heterocyclic synthesis, enabling direct functionalization at the 2- and 5-positions via palladium-catalyzed cross-coupling reactions. The nitro group facilitates subsequent reduction and substitution, while the methyl substituent provides steric and electronic modulation. Its bench-stable crystalline form and predictable reactivity profile support efficient synthesis of complex pyridine-based scaffolds relevant to agrochemical and pharmaceutical development.
