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-Chloro-3,4-dihydroxybenzoic acid features a chlorinated benzene ring with adjacent hydroxyl groups and a carboxylic acid at the para position, enabling strong hydrogen bonding and enhanced solubility in polar solvents. This configuration supports its use in bioactive molecule synthesis, particularly as a scaffold for kinase inhibitors and antioxidant analogs. The electron-withdrawing chlorine stabilizes reactive intermediates during coupling reactions.

Application

2-Chloro-3,4-dihydroxybenzoic acid serves as a versatile building block in medicinal chemistry and natural product synthesis, enabling the construction of bioactive heterocycles and polyphenolic scaffolds. Its ortho-dihydroxy functionality offers strong metal-chelating capacity, while the chloro and carboxylic acid groups provide sites for selective derivatization via coupling, esterification, or nucleophilic substitution reactions. The compound exhibits good bench stability and facilitates purification through standard chromatographic techniques.
