2903.12.00.00 - Dichloromethane (Methylene chloride)

This category specifically classifies Dichloromethane, also commonly known as Methylene Chloride. Dichloromethane is a volatile, colorless liquid with a sweetish odor, primarily characterized by its two chlorine atoms attached to a single carbon atom within an acyclic structure. It falls under the broader group of saturated chlorinated acyclic hydrocarbons, signifying that its carbon-carbon bonds are single and it does not contain any ring structures.

Dichloromethane is distinguished from its sibling categories by its specific chemical composition. For instance, it is separate from Chloromethane and Chloroethane (2903.11.00), which have fewer chlorine atoms. It is also differentiated from Chloroform (2903.13.00.00) and Carbon Tetrachloride (2903.14.00.00) which possess a greater number of chlorine atoms attached to the central carbon. Ethylene dichloride (2903.15.00.00) is also distinct as it contains two carbon atoms in its acyclic structure.

As Dichloromethane (Methylene Chloride) represents a specific, singular chemical compound, this node is a leaf node within the HTS structure, meaning it has no further subcategories. Its classification is based on its precise chemical identity and the number and arrangement of its constituent atoms.
