For procurement managers and technical buyers in the chemical industry, understanding product specifications is paramount to ensuring successful sourcing and application. Dioctyl Maleate (DOM), a versatile chemical intermediate and plasticizer with CAS 142-16-5, is no exception. When looking to purchase DOM, a clear grasp of its key specifications, coupled with the advantages of sourcing from a Chinese manufacturer, can lead to more informed and efficient procurement decisions.

The primary function of Dioctyl Maleate is often related to its performance as a plasticizer and its utility in polymerization. These roles demand a certain level of purity and specific physical and chemical properties to guarantee consistent results. A reputable supplier, particularly a manufacturer in China, will provide detailed documentation outlining these critical parameters.

One of the most crucial specifications is Purity (GC). For Dioctyl Maleate, this typically needs to be ≥99.0%. High purity ensures that the DOM acts as intended, whether it's enhancing flexibility in polymers or participating effectively in copolymerization reactions. Lower purity can lead to unpredictable outcomes, side reactions, and compromised performance in the final product. When you buy Dioctyl Maleate, always confirm the GC purity percentage.

The Appearance is another straightforward yet important indicator. DOM should be a colorless transparent oily liquid. Any deviation in color or clarity might suggest contamination or degradation, indicating a potential issue with storage or manufacturing. This visual cue is often the first check performed upon receiving a shipment, and it aligns with the product description from leading China suppliers.

Acid Value is a critical parameter, usually specified as ≤0.10 mg KOH/g. A low acid value signifies minimal free acidic components, which is important because acidity can potentially catalyze unwanted side reactions or affect the stability of formulations, especially in sensitive applications like coatings and adhesives. Ensuring a low acid value is a hallmark of quality production when you inquire about Dioctyl Maleate price and availability.

Other significant specifications include Moisture Content (typically ≤0.10%), which is vital for many chemical reactions and to prevent hydrolysis, and Color (Pt-Co), which should be low (e.g., ≤30) to indicate a lack of colored impurities. Trans Content (if specified, e.g., ≤3.00%) might also be relevant depending on the synthesis route and intended application, ensuring the desired isomer is predominantly present.

Sourcing Dioctyl Maleate from a Chinese manufacturer often provides a distinct advantage in meeting these specifications reliably and cost-effectively. Chinese chemical producers have invested heavily in advanced manufacturing technologies and quality control systems. They are accustomed to meeting international standards and can provide comprehensive Certificates of Analysis (CoA) for their products. This transparency allows buyers to confidently assess the quality of the DOM before making a purchase decision, and to compare Dioctyl Maleate price points across different reputable suppliers.

In conclusion, understanding the detailed specifications for Dioctyl Maleate (DOM)—from purity and appearance to acid value and moisture content—is essential for any B2B buyer. By partnering with a trusted Chinese manufacturer that adheres to high-quality standards and provides transparent documentation, businesses can ensure they are procuring a chemical intermediate that will consistently deliver the performance required for their demanding industrial applications.
