Description

Oxalic Acid is a versatile and powerful dicarboxylic acid widely utilized across numerous industrial sectors. Its strong chelating and reducing properties make it an essential processing agent for cleaning, bleaching, and purification applications. Key industries that rely on this compound include pharmaceuticals, textiles, metal finishing, and specialty chemical synthesis. We supply high-purity Oxalic Acid CAS NO 68603-87-2 to meet the stringent demands of global B2B markets.

Application

• Metal Cleaning & Surface Treatment: Effective rust remover and polishing agent for ferrous and non-ferrous metals.
• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and fine chemicals.
• Textile & Leather Processing: Acts as a bleaching agent and mordant in dyeing processes for natural fibers.
• Industrial Cleaning Formulations: Key ingredient in specialized cleaners for boilers, heat exchangers, and cooling systems due to its descaling ability.
• Laboratory & Analytical Reagent: Employed in analytical chemistry for standardization and as a precipitating agent.
• Wood & Pulp Bleaching: Used in pulp processing to brighten and remove residual lignin.
• Rare Earth Element Processing: Crucial for the extraction and purification of rare earth metals from ores.

Quality Control

Our Oxalic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets the required specifications for purity, identity, and strength. We can provide material compliant with various pharmacopeial standards (e.g., USP, BP, EP) upon request. A detailed Certificate of Analysis (COA) is available for every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent caking and degradation. Recommended storage temperature is 15-25°C.
