Description

Oxalic Acid is a versatile and essential dicarboxylic acid widely used across multiple industrial sectors. Its strong chelating and reducing properties make it a critical component in cleaning, bleaching, and metal surface treatment processes. Key industries that rely on this compound include pharmaceuticals, textiles, metallurgy, and specialty chemical manufacturing, where consistent purity and reliable supply are paramount.

Application

• Metal Cleaning & Surface Treatment: Effective rust remover and polishing agent for metals like iron and aluminum.
• Pharmaceutical Synthesis: Used as an intermediate or precipitating agent in the production of various active pharmaceutical ingredients (APIs).
• Textile & Leather Processing: Acts as a bleaching agent for textiles and a tanning agent in leather production.
• Industrial Cleaning Formulations: A key ingredient in specialized cleaners and descalers for boilers and cooling systems.
• Rare Earth Element Processing: Employed in the extraction and purification of rare earth metals from ores.
• Wood & Stone Restoration: Used to bleach and clean wood pulp, as well as to remove iron stains from stone surfaces.
• Analytical Chemistry: Serves as a primary standard in analytical titrations and as a reducing agent in laboratory settings.
