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

Methyl 5-bromo-4-fluoro-2-hydroxybenzoate features a trifunctional aromatic core with orthogonal reactivity. The ortho-hydroxyl group enables chelation or derivatization, while the bromo and fluoro substituents serve as handles for palladium-catalyzed cross-coupling and nucleophilic substitution. This electron-deficient scaffold integrates readily into complex molecular architectures under standard conditions.

Application

Methyl 5-bromo-4-fluoro-2-hydroxybenzoate serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling selective functionalization at the hydroxy and carboxylate positions. The ortho-hydroxy group facilitates intramolecular cyclization or metal-catalyzed coupling reactions, while the bromo and fluoro substituents support sequential cross-coupling transformations under mild conditions. Its bench-stable nature and compatibility with standard purification protocols make it well-suited for multi-step synthesis workflows.
