Introduction: Why Is Cyclopentanone Important in Modern Industry? Cyclopentanone (CAS 120-92-3) is an important cyclic ketone used as a chemical intermediate in several industrial sectors, including pharmaceuticals, agrochemicals, fragrance manufacturing, and electronic materials. Its five-membered carbon ring and reactive carbonyl group make it a useful building block for synthesizing more complex organic compounds. As manufacturers seek reliable raw materials for specialty chemical production, Cyclopentanone continues to attract attention for its role in multi-step synthesis, specialty ingredient development, and selected industrial solvent applications. According to established chemical references and manufacturer information, Cyclopentanone is used in pharmaceutical and agrochemical synthesis, fragrance production, and certain electronic applications. Its suitability for a particular process depends on purity, impurity profile, reaction conditions, and downstream requiremen...
1. What Is 4-Ethenylphenol Ace t ate? 4-Ethenylphenol Acetate , also known as 4-Acetoxystyrene or 4-Vinylphenyl Acetate , is an aromatic organic compound used as a building block in polymer chemistry and functional material research. Its CAS Registry Number is 2628-16-2 . The molecule contains a vinyl group attached to an aromatic ring and an acetate-protected phenolic oxygen. This combination makes 4-Ethenylphenol Acetate relevant to researchers developing functional polymers, specialty resins, and materials requiring controlled chemical modification. Unlike compounds containing a free phenolic hydroxyl group, 4-Ethenylphenol Acetate has its phenolic oxygen protected by an acetate group. This structural feature can provide additional flexibility in synthetic route design. For chemical manufacturers, material developers, and R&D teams, understanding its molecular structure, polymerization behavior, and potential applications is essential when evaluating this monomer for a sp...
