Overview

2-methylcyclohexan-1-ol (CAS 583-59-5) is a cyclic secondary alcohol featuring a methyl substituent on the cyclohexane ring structure. This organic compound represents an important member of the cycloaliphatic alcohol family, characterized by its distinctive cyclohexane backbone with both hydroxyl and methyl functional groups. The substance appears as a colorless to pale yellow liquid with a characteristic mild alcoholic odor, demonstrating typical properties associated with secondary alcohols. Its molecular structure combines the stability of a six-membered ring with the reactivity of a secondary alcohol group, making it valuable for various industrial applications. The compound exhibits moderate polarity due to its hydroxyl group while maintaining significant hydrophobic character from its cycloalkane structure. This dual nature allows for versatile solubility properties and chemical reactivity patterns. Unlike simpler alcohols such as hexan-1-ol, the cyclic structure provides enhanced thermal stability and unique steric properties that influence its behavior in chemical reactions and formulations. From a safety perspective, 2-methylcyclohexan-1-ol is classified under Acute Toxicity Category 4, requiring appropriate handling precautions. The compound falls under ADR Class 3 for transportation, indicating its flammable nature. Users must implement proper ventilation, personal protective equipment, and fire prevention measures when handling this material. Industrial applications include its use as a chemical intermediate in organic synthesis, particularly in pharmaceutical and specialty chemical manufacturing. The compound also serves as a solvent component in certain formulations and as a building block for more complex molecular structures. Its unique structural properties make it valuable in the production of fragrances and flavor compounds. OYSI maintains reliable supply chains for 2-methylcyclohexan-1-ol to support diverse industrial requirements across European markets.
