For professionals in the chemical and pharmaceutical industries, securing a reliable supply of high-quality intermediates is paramount. Cyclopentyl Phenyl Ketone (CAS 5422-88-8) is one such compound, recognized for its utility as a pharmaceutical intermediate and its role in advanced organic synthesis. This guide aims to equip procurement managers and research scientists with the knowledge to effectively source this crucial chemical, focusing on quality, competitive pricing, and identifying dependable manufacturers and suppliers.

Cyclopentyl Phenyl Ketone, also known by synonyms like Benzoylcyclopentane, is an aromatic ketone with the molecular formula C12H14O. Its chemical properties, including a boiling point of 136-140°C at 16mm, a density of 1.036 g/cm³, and a refractive index of 1.5440, indicate its suitability for specific synthetic pathways. As a pale yellow liquid, it is generally handled with standard laboratory precautions, with hazard statements like H302 (Harmful if swallowed), H315 (Causes skin irritation), and H319 (Causes serious eye irritation) underscoring the need for proper safety protocols during use and handling.

The primary applications for Cyclopentyl Phenyl Ketone lie in its function as a building block for more complex molecules. It is particularly noted for its use in the preparation of ortho-arylated compounds and phenanthrones through palladium-catalyzed chelation-assisted C-H activation. Furthermore, it is identified as a key intermediate in the synthesis of certain quin ether derivatives. For research and development purposes, understanding these applications helps in evaluating the compound's necessity and potential applications within specific projects.

When looking to buy Cyclopentyl Phenyl Ketone, it is essential to consider the reputation and capabilities of potential suppliers. Identifying a reputable Cyclopentyl Phenyl Ketone supplier in China or other global manufacturing hubs can significantly impact the cost-effectiveness and reliability of your procurement. Look for manufacturers that can provide comprehensive technical data sheets (TDS), Certificates of Analysis (CoA), and Material Safety Data Sheets (MSDS). These documents are critical for ensuring product quality and safety compliance.

The price of Cyclopentyl Phenyl Ketone can vary based on purity, quantity, and the supplier. For bulk procurement, it is advisable to request multiple quotations from different manufacturers to secure the best possible price. Many suppliers offer tiered pricing based on order volume, making it advantageous for businesses to consolidate their purchases. When comparing prices, always factor in shipping costs, lead times, and any import duties or taxes that may apply. For example, while some sources might list prices per milligram for research quantities, industrial-scale buyers will look for price per kilogram from a dedicated pharmaceutical intermediate manufacturer.

To ensure you are purchasing the correct grade and reliably sourcing this chemical, consider establishing a direct relationship with a manufacturer. Companies like NINGBO INNO PHARMCHEM CO.,LTD. specialize in providing such intermediates, focusing on quality control and customer service. By partnering with experienced suppliers, you can streamline your procurement process and gain access to technical support, making your R&D and manufacturing operations more efficient.
