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

3-Chloro-4-hydroxybenzoic acid features a hydroxyl group ortho to the carboxylic acid and a chloro substituent at the para position, delivering enhanced electron withdrawal and improved solubility. This arrangement supports efficient coupling reactions in synthetic routes to bioactive molecules.

Application

3-Chloro-4-hydroxybenzoic acid serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling direct functionalization at the aromatic ring. Its ortho-chloro and para-hydroxyl groups provide complementary reactivity for Suzuki-Miyaura coupling, nucleophilic substitution, and derivatization via esterification or amide formation. The compound exhibits excellent bench stability and facilitates straightforward purification, making it well-suited for multi-step synthetic sequences and scale-up applications.
