For professionals in the pharmaceutical and fine chemical industries, the specifications of chemical intermediates are not mere details; they are fundamental to the success of synthesis and the quality of the end product. 3-Chloro-1,1-diethoxypropane, known by its CAS number 35573-93-4, is a compound where precise specifications are critical. As a key building block, its purity and physical characteristics directly influence reaction yields, purity of the final product, and the overall efficiency of a manufacturing process.

The appearance of 3-chloro-1,1-diethoxypropane is typically described as a colorless to very faint yellow clear liquid. This visual characteristic is an initial indicator of product quality. Any significant deviation, such as cloudiness or a strong off-color, could suggest contamination or degradation, signaling that the material may not meet the required standards for sensitive applications. Buyers should always verify this information with the supplier.

Perhaps the most critical specification is purity, often stated as a minimum percentage. For 3-chloro-1,1-diethoxypropane, a purity of 97% minimum is commonly found. This figure represents the percentage of the desired compound in the bulk material. Impurities, even in small amounts, can interfere with chemical reactions, lead to the formation of unwanted byproducts, and complicate purification steps, ultimately increasing costs and timelines. For pharmaceutical applications, exceeding these purity thresholds is often mandated by regulatory bodies.

When you are looking to buy 3-chloro-1,1-diethoxypropane, it is imperative to request a Certificate of Analysis (CoA) from your chosen manufacturer or supplier. The CoA provides a detailed breakdown of the product's tested specifications, including purity, appearance, and other relevant physical and chemical properties. This document is your assurance that the product meets the stated quality standards.

Moreover, understanding the storage conditions recommended by the supplier is also part of ensuring product integrity. For 3-chloro-1,1-diethoxypropane, storage at 2-8°C, sometimes with a stabilizer like sodium carbonate, is often advised. Proper storage maintains the compound's quality over time, ensuring it remains fit for purpose. By focusing on these key specifications and working with reputable suppliers who provide clear documentation, you can confidently procure 3-chloro-1,1-diethoxypropane for your critical synthesis needs.
