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

Description

2,4-Dibromo-5-methylpyridine features a pyridine core substituted with bromine atoms at the 2- and 4-positions and a methyl group at the 5-position, delivering enhanced electrophilicity for cross-coupling reactions. The para-bromo and ortho-bromo sites enable selective functionalization in palladium-catalyzed transformations, while the methyl group provides steric and electronic modulation. This scaffold integrates efficiently into complex heterocyclic architectures under standard conditions.

Application

2,4-Dibromo-5-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 positions. The methyl group enhances regioselectivity in electrophilic substitution, while the dibromopyridine core provides orthogonal reactivity for sequential functionalization. Bench-stable and compatible with standard purification techniques, it facilitates efficient construction of complex heterocyclic scaffolds in multi-step syntheses.
