For professionals in the chemical and manufacturing industries, a thorough understanding of the properties of key raw materials is fundamental to successful product development and consistent production. Diphenylmethane (CAS 101-81-5), a compound known by synonyms such as benzylbenzene, is a versatile aromatic hydrocarbon with a range of physical and chemical characteristics that dictate its suitability for various applications. As a leading chemical supplier, NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality Diphenylmethane and aims to educate our clients on what makes it an essential component for many industries.

Physically, Diphenylmethane typically presents as a colorless to pale yellow solid or liquid, depending on the ambient temperature. With a melting point range of approximately 22-25°C, it can exist in either state under typical laboratory or industrial conditions. Its boiling point is around 265°C, indicating relatively low volatility at room temperature. In terms of solubility, it is generally insoluble in water but soluble in common organic solvents like ethanol, ether, and benzene. The density is approximately 1.006 g/cm³ at 20°C. These physical attributes are important for handling, storage, and incorporation into various formulation and reaction processes.

Chemically, Diphenylmethane's most notable feature is the methylene group (-CH2-) bridging the two phenyl rings. This linkage makes the hydrogen atoms on the methylene carbon mildly acidic, with a pKa of 32.2, allowing for deprotonation and subsequent alkylation reactions. This reactivity is key to its role as an intermediate in organic synthesis. Furthermore, it is stable under normal conditions but should be protected from strong oxidizing agents. Understanding these chemical behaviors is crucial for chemists when designing synthesis routes or incorporating Diphenylmethane into formulations.

When procuring Diphenylmethane, buyers should pay close attention to several specifications. The purity level, typically indicated by Gas Chromatography (GC) analysis, is paramount, with ≥99% purity being a common standard for high-grade material used in pharmaceuticals and fine fragrances. The CAS number (101-81-5) is the universal identifier, ensuring you are sourcing the correct compound. As a potential buyer, it is advisable to buy Diphenylmethane manufacturer direct, particularly from a reputable supplier in China like NINGBO INNO PHARMCHEM CO.,LTD., to ensure quality and competitive pricing. Requesting a Certificate of Analysis (CoA) is a standard practice to verify lot-specific properties and purity.

The diverse applications of Diphenylmethane in industries ranging from fragrances and dyes to pharmaceuticals and agrochemicals underscore its importance. By understanding its properties and ensuring you purchase Diphenylmethane from a trusted manufacturer, you can confidently integrate this versatile chemical into your operations.
