Oxalic Acid

Product Overview

Oxalic Acid is an organic dicarboxylic acid used in selected industrial cleaning, rust-removal, metal-treatment, textile-processing, and chemical applications. It can react with certain metal oxides and mineral deposits, making it useful in carefully formulated cleaning and surface-treatment processes.

Oxalic Acid is available in different forms, including anhydrous oxalic acid and oxalic acid dihydrate. These forms differ in molecular weight and active acid content by mass, so the exact grade and hydrate form should be confirmed before formulation calculations.

MNTENT.com makes selected chemical raw materials available in small quantities for testing, formulation trials, product development, and technical evaluation, subject to availability.
