For professionals in the chemical and pharmaceutical industries, a thorough understanding of product specifications is crucial before making a purchase. Disodium laureth sulfosuccinate, also known as disodium C-[2-[2-[2-(dodecyloxy)ethoxy]ethoxy]ethyl] sulphonatosuccinate (CAS 42016-08-0), is a compound that demands careful attention to its quality parameters. As a manufacturer, we aim to provide clarity on these specifications to empower our clients' purchasing decisions.

The primary specification for any chemical intermediate is its purity. For disodium laureth sulfosuccinate, a minimum assay of 99.5% is often indicative of a high-grade product suitable for demanding applications. This purity level ensures that the compound can perform reliably in synthesis reactions without introducing unwanted side products or inhibiting critical steps. Furthermore, when considering pharmaceutical applications, adherence to pharmacopeial standards like USP, BP, and EP is non-negotiable. These standards dictate not only the chemical purity but also limits on impurities and other quality attributes.

The appearance of disodium laureth sulfosuccinate is another important specification. Typically, it is described as a colorless transparent liquid. Any deviation from this description, such as significant coloration or turbidity, might suggest degradation or contamination, prompting further investigation. Suppliers should be able to provide photographic evidence or allow for sample inspection to confirm the visual quality.

Beyond purity and appearance, understanding the intended application is key. While often referred to as a surfactant raw material, its primary value for many industrial clients lies in its role as a chemical intermediate. This means it's used as a building block in the synthesis of more complex molecules. For those looking to buy disodium C-[2-[2-[2-(dodecyloxy)ethoxy]ethoxy]ethyl] sulphonatosuccinate for synthesis, ensuring the supplier's manufacturing process is well-controlled and documented is vital.

When sourcing from China, potential buyers should inquire about the supplier's manufacturing capabilities and quality control measures. A direct manufacturer will be able to provide detailed information about their production processes and quality assurance protocols. Comparing prices from different suppliers is also a common practice, but it should always be balanced against the quality and reliability offered. Seeking out a manufacturer that also offers online purchase support can simplify the procurement process.

In conclusion, when purchasing disodium laureth sulfosuccinate (CAS 42016-08-0), paying close attention to purity (assay), appearance, and compliance with relevant industry standards is essential. By partnering with a reputable manufacturer that prioritizes quality and offers transparent specifications, businesses can confidently acquire this valuable chemical intermediate for their critical applications.
