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

5-Bromo-4-methyl-3-pyridinol features a bromine substituent at the 5-position and a methyl group at the 4-position on a pyridinol scaffold, enabling selective functionalization in heterocyclic synthesis. The phenolic hydroxyl enhances reactivity for coupling reactions, while the electron-deficient ring facilitates transition metal-catalyzed transformations. This bench-stable compound serves as a key intermediate in medicinal chemistry and agrochemical development.

Application

5-Bromo-4-methyl-3-pyridinol serves as a versatile building block in heterocyclic synthesis, enabling palladium-catalyzed cross-coupling reactions due to its bromine substituent. The pyridinol core provides a stable, bench-accessible platform for further functionalization, with the methyl group offering mild directing effects. Its compatibility with standard reaction conditions facilitates integration into complex molecular architectures relevant to medicinal chemistry and agrochemical development.
