For procurement professionals and product formulators in the chemical and personal care industries, selecting high-quality raw materials is critical. Ethyl butylacetylaminopropionate (CAS 52304-36-6) is a prime example of an ingredient where precise specifications directly translate to product efficacy and safety, particularly in insect repellent applications. This guide outlines the key quality parameters to consider when you buy Ethyl butylacetylaminopropionate from manufacturers and suppliers.

The most fundamental specification to verify is the assay or purity of the Ethyl butylacetylaminopropionate. Reputable manufacturers, especially those in China known for their chemical production capabilities, typically offer a purity level of ≥98.0% (GC). Gas Chromatography (GC) is the standard method for determining purity and identifying trace impurities. High purity ensures that the active ingredient performs optimally in your formulations and minimizes the risk of unintended side reactions or adverse effects.

Appearance is another crucial characteristic. Ethyl butylacetylaminopropionate should be described as a clear, colorless to light yellow liquid. Any deviation from this, such as cloudiness or a distinct color, could indicate contamination or degradation, suggesting that the product may not meet quality standards. When you purchase this ingredient, always cross-reference the supplier's description with the Certificate of Analysis (CoA).

Other important specifications include the refractive index, which is a measure of how light bends as it passes through the substance, and sulphate ash content, which indicates the amount of inorganic impurities. For Ethyl butylacetylaminopropionate, a typical refractive index range is provided (e.g., 1.4525~1.4555 at 25°C), and a low sulphate ash percentage (≤0.1%) is desirable. These parameters contribute to the overall consistency and quality of the material.

Furthermore, checking the pH value (often around 4.0-6.0 for a 5% solution), water content (≤0.50%), and heavy metals content (e.g., ≤0.002% for lead) are vital for safety and formulation stability. Microbiological testing (cfu/ml ≤100) is also important, especially for ingredients used in personal care products. When you are looking to buy Ethyl butylacetylaminopropionate, engaging directly with a manufacturer or a trusted supplier allows you to request and review these detailed specifications.

Sourcing from a reputable China manufacturer often provides competitive pricing alongside rigorous quality adherence. By understanding and demanding these key specifications, procurement professionals can ensure they are obtaining high-quality Ethyl butylacetylaminopropionate that will contribute to the success of their insect repellent products. Prioritize suppliers who provide comprehensive documentation and demonstrate a commitment to quality at every step.
