For professionals in the chemical and pharmaceutical industries, a thorough understanding of product specifications is fundamental to successful procurement and application. 4,4'-Dimethoxybenzophenone (CAS 90-96-0) is a versatile chemical intermediate with critical roles in various synthesis processes. Ensuring you are sourcing the correct grade and quality is essential. This article outlines the key specifications to scrutinize when purchasing this compound, empowering buyers with the knowledge to make informed decisions and select the most reliable suppliers.

Key Specifications of 4,4'-Dimethoxybenzophenone

When you buy 4,4'-Dimethoxybenzophenone, several technical parameters are commonly provided by manufacturers. These specifications help define the product's suitability for your intended use:

• CAS Number: 90-96-0 is the unique identifier for 4,4'-Dimethoxybenzophenone, ensuring you are referencing the correct chemical substance.
• Molecular Formula: C15H14O3. This indicates the elemental composition of the molecule.
• Molecular Weight: Approximately 242.27 g/mol. This figure is important for stoichiometric calculations in chemical reactions.
• Appearance: Typically described as a White to Off-White Solid or White crystal powder. Any significant deviation from this could indicate impurities or degradation.
• Purity: This is arguably the most critical specification, especially for pharmaceutical intermediates. High-purity grades, usually 99% minimum (often verified by Gas Chromatography - GC), are essential for consistent performance and minimizing side reactions. Suppliers should be able to provide Certificates of Analysis (CoA) detailing purity levels and the presence of any specific impurities.
• Melting Point: Generally reported in the range of 141-145 °C (literature values may vary slightly). A sharp melting point within the specified range is indicative of high purity.
• Solubility: Often described as slightly soluble in chloroform and ethyl acetate, and insoluble in water. This information is helpful for chemists planning reaction conditions or purification steps.

Understanding Application-Specific Requirements

While standard specifications are crucial, consider your specific application's needs. For pharmaceutical synthesis, an extremely high purity and strict control over specific impurities are paramount. For polymer stabilization, consistency in UV absorption characteristics is key. When engaging with a 4,4'-Dimethoxybenzophenone manufacturer or supplier, be prepared to discuss your application to ensure the provided material fully meets your requirements. For example, if you are purchasing for organic synthesis, understanding the reactivity and potential side products associated with a particular purity grade is vital.

The Importance of a Reliable Supplier

Choosing a supplier that transparently provides accurate specifications and supports their product with reliable documentation is paramount. When looking to buy 4,4'-Dimethoxybenzophenone, focus on manufacturers who can consistently deliver material meeting these detailed specifications. A trusted chemical supplier will be your partner in ensuring the success of your research and production processes, providing the high-quality intermediates necessary for critical applications.
