Overcoming Industrial Cleaning Challenges with Oxalic Acid Dihydrate CAS 144-62-7
We've witnessed countless production delays caused by inconsistent chemical purity—leather tanneries struggling with uneven dye absorption, stone processing plants facing residue buildup, and laboratories unable to replicate critical reactions. When Oxalic Acid Dihydrate purity drops below 99.5%, the cleaning efficiency plummets by up to 30%, forcing rework and material waste that erodes profit margins.
Stable Supply of High-Purity Tech Grade Oxalic Acid
Our Oxalic Acid Dihydrate (CAS 144-62-7) delivers consistent 99.6% purity, eliminating the variability that disrupts industrial processes. Backed by 10+ years of chemical export experience and serving over 6,000 global industrial customers, we ensure reliable availability through a 5000 Tons/Month production capacity, specifically tailored for leather processing and stone cleaning applications.
Key Industrial Applications
This Industrial Dicarboxylic Acid plays a pivotal role in leather processing as a deliming agent, effectively removing lime residues to prepare hides for tanning. In stone cleaning, its chelating properties dissolve mineral deposits and rust stains without damaging the substrate. Additionally, it serves as a reducing agent in mining operations and metal surface treatment, demonstrating versatility across multiple industrial sectors.
Critical Specifications for Optimal Performance
The 99.6% purity level minimizes impurities that cause unwanted side reactions in leather processing, ensuring uniform pH control during deliming. Its defined melting point (101-102ºC) guarantees consistent dissolution behavior in aqueous solutions, a critical factor for stone cleaning formulations. The medium strong acidity strikes the perfect balance—effective enough to remove tough stains yet controlled to prevent material etching. As a dicarboxylic acid, its molecular structure provides superior chelation capabilities compared to monocarboxylic alternatives, enhancing cleaning efficiency in industrial settings.
Quality Assurance: From Production to Delivery
Choosing substandard Oxalic Acid Dihydrate risks equipment corrosion, product defects, and regulatory non-compliance. Our ISO9001-certified manufacturing process ensures each batch meets strict quality parameters, with SGS-audited facilities maintaining REACH compliance for European markets. The 25kg packaging is designed for safe transport and easy handling, reducing contamination risks during storage. By maintaining consistent quality, we help customers avoid the hidden costs of rework, material waste, and production downtime associated with inferior chemicals.
Our Commitment to Reliability
Every shipment undergoes rigorous testing using HPLC and titration methods, with each batch accompanied by a detailed Certificate of Analysis (COA). Our quality control laboratory operates 24/7 to monitor production, ensuring batch-to-batch consistency. We offer a full refund or replacement for any product failing to meet specifications, supported by our dedicated technical team available for pre-purchase consultations and post-delivery support. With multiple loading ports (Qingdao, Tianjin, Shanghai), we optimize logistics to meet your delivery timelines even during peak seasons.
Certificate of Analysis & Documentation
Each delivery includes a batch-specific COA with purity test results, pH value, and heavy metal content analysis. MSDS documents are provided in multiple languages, detailing safe handling procedures and emergency protocols. For critical applications, we can arrange third-party testing through SGS or Intertek at customer request, with full access to raw检测 data upon order verification.
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.
Simple Ordering Process for Industrial Buyers
Begin by submitting an inquiry with your required quantity and delivery timeline. We'll provide a detailed quotation including FOB/CIF pricing options and arrange sample delivery for qualification testing. Once specifications are confirmed, our team coordinates production scheduling and documentation to ensure smooth customs clearance. Regular customers benefit from dedicated account managers and priority production slots during high-demand periods.
