Product Technical Details

Product Overview

3-Hydroxybenzoic Acid, also known as meta-Hydroxybenzoic Acid, is a crucial organic compound widely utilized in the chemical synthesis industry. As a structural isomer of hydroxybenzoic acid, it features a hydroxyl group positioned at the meta location on the benzene ring relative to the carboxylic acid group. This specific arrangement imparts unique chemical reactivity, making it an indispensable building block for various agrochemical and pharmaceutical applications. Our facility produces this compound using advanced organic synthesis techniques to ensure consistent quality and high purity levels suitable for demanding industrial processes.

We understand that reliability in the supply chain is paramount for manufacturing operations. Therefore, we maintain strict quality control protocols throughout the production cycle. From raw material selection to final packaging, every batch undergoes rigorous testing to verify compliance with international standards. This commitment ensures that our clients receive a product that performs predictably in their downstream synthesis routes, minimizing variability and maximizing yield.

Industrial Applications

The primary application of 3-Hydroxybenzoic Acid lies in the synthesis of agrochemical intermediates. It serves as a key precursor in the manufacturing of Fomesafen, a widely used herbicide effective against broadleaf weeds. The high purity of our product ensures efficient coupling reactions and reduces the formation of unwanted by-products during the synthesis of such complex molecules. Beyond pesticides, this compound finds utility in the preparation of various organic esters and polymers.

For research and development teams, having access to a reliable source of this intermediate is essential for scaling up processes from laboratory to pilot plant. Our material supports diverse synthetic pathways, including esterification and amidation reactions. The consistent particle size and low moisture content facilitate easier handling and dissolution in common organic solvents, streamlining the production workflow for our partners.

Quality Assurance and Logistics

We prioritize safety and integrity in every shipment. Each drum is sealed to prevent moisture absorption and contamination during transit. Standard packaging consists of 25 kg fiber drums, though we offer flexible packaging solutions tailored to customer logistics needs. A Certificate of Analysis (COA) is provided with every batch, detailing the specific test results for purity, moisture, and identity confirmation.

Proper storage is essential to maintain product stability. We recommend storing 3-Hydroxybenzoic Acid in a cool, ventilated area away from direct sunlight and incompatible materials. Our global distribution network ensures timely delivery to major chemical hubs worldwide.
