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

4-Bromo-5-methylpyridin-2-amine features a pyridine core functionalized with bromo and methyl groups at adjacent positions, enabling selective cross-coupling reactions. The electron-deficient nitrogen atom facilitates metal coordination, while the para-arranged substituents provide steric and electronic control. This scaffold integrates readily into bioactive heterocycles and serves as a key intermediate in medicinal chemistry.

Application

4-Bromo-5-methylpyridin-2-amine serves as a versatile building block for the synthesis of bioactive heterocycles and pharmaceutical intermediates. Its bromo group enables palladium-catalyzed cross-coupling reactions, while the pyridin-2-amine functionality offers sites for further functionalization via electrophilic substitution or metal complexation. The methyl substituent enhances solubility and modulates electronic properties, contributing to improved stability and reactivity in standard synthetic workflows.
