For any chemist or product formulator, a thorough understanding of chemical specifications is the bedrock of successful application. 5-Chloro-1-pentene (CAS 928-50-7) is a key intermediate, and its precise characteristics dictate its utility in various synthesis pathways. Delving into its specifications, such as appearance, purity, and physical properties, is essential for procurement managers and R&D scientists alike.

The most commonly cited specification for 5-Chloro-1-pentene is its appearance: a colorless transparent liquid. This physical characteristic is a good initial indicator of product quality. Deviations from this description, such as turbidity or unusual color, could signal potential contamination or degradation. When you buy 5-Chloro-1-pentene, always expect this clarity.

Purity is arguably the most critical specification for any chemical intermediate. For 5-Chloro-1-pentene, a typical standard is purity levels of ≥97.0%. This assay is vital because impurities can interfere with reaction kinetics, yield, and the quality of the final product. Manufacturers often provide a detailed Certificate of Analysis (CoA) that confirms the exact purity and the levels of any trace impurities. When inquiring about price or seeking to purchase, always request this vital document.

Beyond appearance and purity, physical properties offer further insight into handling and application. The reported boiling point of 101.8°C at 760 mmHg and a flash point of 7.3°C are important for understanding its volatility and flammability, crucial for safe handling and storage. Its density (0.889 g/cm³) and refractive index (1.42) are also standard data points used for identification and quality checks. These properties are consistently detailed by suppliers when you look to buy this compound.

For professionals in industries requiring this specific building block, such as pharmaceutical intermediate manufacturing, ensuring that your supplier provides accurate and verifiable specifications for 5-Chloro-1-pentene is paramount. Whether you are conducting laboratory research or scaling up production, understanding these details will empower you to make informed purchasing decisions and achieve optimal results.
