Oxalic Acid CAS 144-62-7: Addressing Stone Cleaning Industry Challenges with Consistent Quality
After a decade of serving stone processing plants across 50+ countries, we’ve witnessed how inconsistent oxalic acid purity disrupts cleaning operations—leaving streaks on marble surfaces or failing to dissolve mineral deposits. Clients often report batch-to-batch variations causing unpredictable results, while delayed shipments from unstable suppliers halt production lines for weeks.
A Stable and Reliable Chemical Supply Solution
Our Industrial Grade Oxalic Acid (CAS 144-62-7) solves these pain points through 99.6% minimum purity and strict quality control. As a leading chemical export platform with 10+ years of experience, we ensure every batch meets the same high standards, supported by a monthly production capacity of 6000 tons to guarantee on-time delivery for large-scale stone cleaning operations.
Typical Industrial Applications
This dicarboxylic acid is widely used in industrial stone cleaning for removing rust stains, mineral deposits, and efflorescence from granite, marble, and concrete surfaces. Its strong chelating properties make it effective in metal surface treatment, leather processing, and as a reducing agent in mining operations. All applications are strictly limited to industrial manufacturing processes.
Why Key Specifications Matter
The 99.6% purity level minimizes impurities that cause surface discoloration in stone cleaning, ensuring consistent results across production runs. Its defined melting point (101-102ºC) allows precise temperature control during dissolution, critical for formulating stable cleaning solutions. The medium strong acidity strikes a balance between effective stain removal and material safety, while solubility in water and ethanol enables versatile formulation options for different cleaning equipment.
What You Gain With Our Product
Choosing ISO9001 and SGS-certified Oxalic Acid reduces production risks compared to uncertified alternatives. Inferior products with lower purity often contain heavy metal residues that damage stone surfaces and fail environmental compliance checks. Our consistent supply eliminates production delays, while bulk packaging options (25kg bags) optimize storage and handling costs—delivering long-term value through reliable performance and regulatory compliance.
Why You Can Trust Us
Every batch undergoes rigorous testing via HPLC and titration methods to verify purity and composition. We provide a Certificate of Analysis (COA) with each shipment, detailing key parameters like assay, moisture content, and heavy metal levels. Our production facility in Shandong adheres strictly to ISO9001 standards, with full traceability from raw material sourcing to final packaging. If specifications don’t match our COA, we offer unconditional replacement or refund—no questions asked.
Certificate of Analysis & Documentation
Each delivery includes a batch-specific COA and MSDS, providing detailed safety and handling information required for industrial use. For quality verification, customers can request access to raw检测数据 by referencing their order number. Additional technical documentation, including material safety guidelines and application recommendations, is available upon request.
Storage & Handling
- Store in a cool, dry, well-ventilated area, sealed and away from direct sunlight.
- Keep away from incompatible materials, food and feed sources.
- Handle with appropriate personal protective equipment (gloves, goggles, lab coat).
- Follow good industrial hygiene practices. Avoid inhalation and skin contact.
- Refer to MSDS for detailed storage and safety instructions.
How to Place Your Order
Start by submitting an inquiry with your required quantity and delivery location. We’ll provide a quotation based on current market conditions and your preferred trade terms (FOB/CIF). For first-time clients, we recommend requesting a sample for testing before placing bulk orders. Once specifications are confirmed, we’ll arrange production, inspection, and shipment from Qingdao, Tianjin, or Shanghai ports—ensuring full documentation for customs clearance.
