For professionals in research and development, and quality control within the chemical industry, ensuring the precise specifications of chemical intermediates is fundamental. 1,3-Propanediol, 2,2-bis(hydroxymethyl)-, allyl ether (CAS 91648-24-7) is no exception. Sourcing this compound requires a thorough understanding of its key quality parameters to guarantee its suitability for demanding applications like polymer synthesis. NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the importance of these parameters for both manufacturers and end-users.

The most critical parameter is the Assay, which indicates the purity of the desired compound. For CAS 91648-24-7, a typical specification is ≥99.0%. This high purity ensures predictable reactivity and minimizes the presence of unwanted byproducts that could interfere with polymerization processes or affect the final polymer properties. When you buy this allyl ether, always check the Certificate of Analysis (CoA) for the reported assay value, usually determined by Gas Chromatography (GC).

The Appearance is another straightforward yet important indicator. The compound is described as a 'Clear colorless liquid.' Any deviation from this, such as cloudiness, discoloration, or the presence of particulate matter, could signal impurities or degradation, suggesting improper handling or storage. As a manufacturer committed to quality, we ensure our product consistently meets this visual standard.

Other significant specifications include the Hydroxyl value, typically measured in mg KOH/g, which indicates the concentration of hydroxyl groups available for reaction. For this allyl ether, the range is usually between 230-260 mg KOH/g. The Peroxide content, often measured in ppm of active oxygen, should be kept to a minimum (≤20 ppm) as peroxides can initiate unwanted radical polymerization.

The Ether Content, specified as ≥98.0% by weight, and the distribution of diallyl, triallyl, and tetraallyl ether content are also crucial. Specifically, the mixture commonly used has a mass percentage of pentaerythritol allyl ether between 70 and 90%, with triallyl ether content being a significant portion. These values are critical for formulators to understand the precise reactive capabilities of the material. Gas Chromatography (GC) is the standard analytical method for determining these isomer ratios.

When you are ready to buy 1,3-Propanediol, 2,2-bis(hydroxymethyl)-, allyl ether, partnering with a reputable manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. ensures you receive material that meets these rigorous specifications. We adhere to strict quality control protocols throughout our manufacturing and packaging processes, providing you with the confidence that our product will perform as expected in your applications. Understanding these quality parameters is the first step towards a successful and productive collaboration.
