Navigating the procurement of industrial chemicals requires a clear understanding of product specifications, purity levels, and essential identifiers like CAS numbers. For Dimethyltetradecylamine (CAS 112-75-4), a vital tertiary amine, these details are crucial for B2B buyers to ensure they acquire a material suitable for their specific applications. This guide aims to clarify what buyers should look for when purchasing this compound from manufacturers and suppliers.

The Chemical Abstracts Service (CAS) registry number, 112-75-4, is a unique numerical identifier for Dimethyltetradecylamine. This number is universally recognized and is the most reliable way to identify the specific chemical substance, eliminating ambiguity. When making inquiries, always specify the CAS number to ensure you are discussing the correct product.

Purity is a cornerstone specification, particularly for Dimethyltetradecylamine. The referenced material typically indicates a purity of 98% or higher. This high purity is essential for many applications, especially in the synthesis of cationic surfactants and for use in sensitive formulations like cosmetics and pharmaceuticals. Lower purity grades might be acceptable for certain less demanding industrial uses, but it's vital to understand the implications for product performance. Manufacturers usually provide a Certificate of Analysis (COA) detailing the exact purity and any significant impurities present.

Beyond general purity, specific parameters such as the concentration of tertiary amine, levels of primary and secondary amines, and residual alcohol content are important. For instance, a typical specification might list a tertiary amine content of ≥98.0% and primary/secondary amines ≤0.3%. These specifications directly influence the chemical's reactivity and suitability for particular reactions, such as quaternization for surfactant production.

Appearance is another key visual indicator. Dimethyltetradecylamine is commonly described as a light yellow to yellow liquid, or a colorless clear liquid depending on the grade and source. While subjective, significant deviations from this description can indicate product degradation or contamination.

When engaging with manufacturers or suppliers, especially those based in China, it's beneficial to inquire about their production capabilities and quality control measures. Are they ISO certified? Do they adhere to specific industry standards? Asking about the packaging options (e.g., 160kg drums, 800kg IBCs) and available quantities is also practical for planning logistics and inventory management. For price inquiries, provide specific quantities and purity requirements to receive accurate quotes.

In essence, a well-informed buyer will scrutinize the CAS number, purity, key specifications, and accompanying documentation like COAs and MSDS. By understanding these elements, B2B professionals can confidently purchase Dimethyltetradecylamine, ensuring they receive a product that meets their exact needs and contributes to the success of their operations.
