1. We carry IPA pharma grade solvent which can be regarded pharma-grade and it is of industrial-grade with purity >=99.7%. It can satisfy the demands both of industrial and laboratory analyses, respectively.
2. Our isopropyl alcohol features moisture ≤0.1%, free of impurities, very stable, acidic ≤0.002%. Thus there is virtually zero interference and the product is quite stable.
3. We have developed solid relationships with major players in the petrochemical industry and we also keep sufficient safety inventory to allow us be able to support our customers all the time no matter how the prices are changing.
In electronic cleaning, pharmaceutical extraction, and fine synthesis, the moisture, acidity, and metal ion content of 2-Propanol directly affect process results. Excessive moisture in IPA directly leads to water marks on the wafer surface, causing a decrease in chip yield.
To address the above issues, each batch of 2-Propanol we manufacture strictly according to the superior grade standard of GB/T 7814-2017: purity ≥99.7% (industrial grade), moisture ≤0.1% (conventional)/≤0.01% (electronic grade), acidity ≤0.002%, evaporation residue ≤0.002%, and metal ion detection data (ICP-MS report) can be provided upon request. With each delivery, we will add a full Certificate of Analysis (COA) as part of the assurance process, which will also validate that the processes were in a stable regimen for cleaning, synthesis, and formulation.

Product Quality and Testing System
Our Isopropyl Alcohol 99 strictly adheres to the standardized quality control system of GB/T 7814-2017 "Industrial Isopropyl Alcohol". This standard specifies the technical requirements, test methods, inspection rules, and marking, packaging, transportation, and storage of industrial isopropyl alcohol. All products have passed the inspection of the manufacturer's quality inspection department, and each batch of products is accompanied by a quality certificate containing information such as product name, product grade, and batch number. From experience, we know that one of the best ways of guaranteeing quality is by having more than one person in the quality control process. So, we created a three-step quality control process: Factory inspection, warehousing re-inspection and a random check-up by the CNAS accreditation laboratory. This way you can be assured that all key physical properties of the product will either meet or possibly surpass the industry level. A complete batch traceability system is in place for each batch of products, and we can provide COA (Certificate of Analysis), MSDS (Material Safety Data Sheet), and technical parameter documents to meet industrial procurement and export compliance requirements.
Supply Capacity and Stability
Relying on a long-term and stable upstream chemical resource system, we maintain continuous cooperation with large domestic petrochemical enterprises to ensure a reliable and consistent supply of isopropanol. Considering the high volatility, combustibility, and the strict requirement of having the storage area explosion-proof and sealed for isopropanol, we set up a system routine for cool, ventilated, and sealed explosion-proof storage with strict regular testing and control turnover to guarantee product purity and moisture levels meet consistently industrial application standards. With our versatile warehousing and allocation capacity, we can swiftly handle the orders based on the clients' production plans, thus, considerably shortening delivery time. Besides traditional order-based procurement, spot, emergency supplies and raw material stability are some of our major strength, helping reduce supply chain risks associated with raw material fluctuations and thereby guaranteeing continuous operations.
