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-Chloro-5-methylpyridin-2-amine features a pyridine core functionalized with chlorine and methyl groups at the 4- and 5-positions, respectively, enabling tailored reactivity in cross-coupling and medicinal chemistry applications. The ortho-chloro substituent enhances electrophilic engagement, while the para-methyl group provides steric and electronic modulation. This scaffold serves as a key building block for kinase inhibitors and agrochemicals, offering robust stability under standard conditions.

Application

4-Chloro-5-methylpyridin-2-amine serves as a versatile building block in medicinal chemistry, enabling efficient construction of pyridine-based heterocycles via palladium-catalyzed cross-coupling reactions. Its chloro group facilitates Suzuki, Stille, and Buchwald–Hartwig couplings, while the pendant amine and methyl substituents provide orthogonal reactivity for further functionalization. The compound exhibits good bench stability and ease of purification, making it well-suited for iterative synthesis workflows in API development.
