Methylnaphthalene (CAS 1321-94-4) is an organic compound that, while perhaps not a household name, is a cornerstone in numerous industrial chemical processes. Belonging to the family of aromatic hydrocarbons, its structure and inherent properties make it a valuable intermediate. This article explores the fundamental chemistry of Methylnaphthalene and its considerable industrial significance, offering insights for professionals in the field.

At its core, Methylnaphthalene is a derivative of naphthalene, featuring a methyl group (CH3) attached to the naphthalene ring system. The chemical formula C11H10 accurately represents its composition, with a molecular weight of 142.1971. The presence of the methyl group distinguishes it from naphthalene itself and imparts specific characteristics that are exploited in various downstream syntheses.

Physically, Methylnaphthalene presents as a colorless to pale yellow oily liquid, often possessing a distinctive naphthalene-like odor. Its solubility profile is typical of many aromatic hydrocarbons: insoluble in water but readily soluble in organic solvents like ether and ethanol. This characteristic is crucial when considering its use as a solvent or reactant in organic chemistry.

Key physicochemical properties are critical for industrial applications. Methylnaphthalene has a melting point of approximately 34°C, meaning it is solid at cooler ambient temperatures but readily becomes a liquid. Its boiling point is significantly higher, around 229.78°C, which allows it to be used in applications requiring elevated temperatures, such as heat transfer fluids. The density is around 1.025 g/cm³. These parameters are meticulously documented by reputable manufacturers like NINGBO INNO PHARMCHEM CO.,LTD., ensuring that buyers receive precise technical data when they purchase Methylnaphthalene.

The industrial significance of Methylnaphthalene is largely tied to its role as an intermediate. Its structure allows for further chemical modification, making it a building block for more complex molecules. The synthesis of disperse dye additives, where it functions as a dispersant, is a prime example. This application underscores its importance in the textile and coloration industries. Manufacturers seeking consistent quality for these demanding applications will find that sourcing high-purity Methylnaphthalene is essential.

Furthermore, its utility extends to being a solvent, a heat carrier, and a precursor for surfactants and plasticizers. The ability to buy Methylnaphthalene that meets specific purity standards from established suppliers like NINGBO INNO PHARMCHEM CO.,LTD. ensures that these diverse applications can be realized effectively and efficiently. The competitive pricing and reliable supply chains offered by such manufacturers further enhance its industrial appeal.

In essence, the chemistry of Methylnaphthalene, characterized by its aromatic structure and functional methyl group, underpins its diverse industrial utility. Understanding its properties is fundamental for chemical engineers, researchers, and procurement specialists.
