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

2-Bromo-4-hydroxybenzoic acid features a bromine substituent at the ortho position relative to the carboxylic acid, combined with a para-oriented hydroxyl group, enabling versatile functionalization in synthetic routes. The electron-withdrawing bromine enhances electrophilic reactivity, while the phenolic hydroxyl supports hydrogen bonding and metal chelation. This dual functionality facilitates integration into pharmaceutical intermediates and advanced materials.

Application

2-Bromo-4-hydroxybenzoic acid serves as a versatile building block for the synthesis of bioactive heterocycles and pharmaceutical intermediates. The ortho-bromo and para-hydroxyl groups enable selective functionalization via palladium-catalyzed cross-coupling and directed ortho-metalation. Its stability under standard reaction conditions and compatibility with common protecting group strategies facilitate efficient downstream transformations in medicinal chemistry workflows.
