4'-Chloroacetophenone, identified by its CAS number 99-91-2, is a vital chemical intermediate with a significant presence in several key industries, most notably pharmaceuticals and fine chemicals. Understanding its properties, applications, and the best practices for sourcing is crucial for any chemist, formulator, or procurement manager. As a leading 4-chloroacetophenone manufacturer in China, we aim to provide clarity on this important compound.

Chemically, 4'-Chloroacetophenone is an aromatic ketone characterized by a chlorine atom substituted at the para position of the phenyl ring of acetophenone. Its molecular formula is C8H7ClO, and it typically appears as a colorless to pale yellow liquid or a white crystalline solid, with a melting point often cited around 14-18°C or 23-25.5°C, meaning it can exist in different states depending on ambient temperature. Its purity, commonly specified as 99.0% or higher by Gas Chromatography (GC), is a critical parameter for its use in sensitive synthesis pathways.

The applications of 4'-Chloroacetophenone are diverse and impactful. In the pharmaceutical industry, it serves as a key intermediate in the synthesis of various Active Pharmaceutical Ingredients (APIs), contributing to the development of therapeutics for a range of medical conditions. Beyond pharmaceuticals, it is also used in the creation of fluorescent whitening agents, which are common additives in detergents, paper, and textiles to enhance visual brightness. Furthermore, its role as a versatile building block extends to general fine chemical synthesis and research applications, where its reactive functional groups can be manipulated for various organic transformations.
