Overview
2-Methylcyclohexanecarboxylic acid is a cycloaliphatic carboxylic acid with a molecular formula of C8H14O2. It is commonly used as an intermediate in the synthesis of pharmaceuticals, fragrances, and other organic compounds. The compound is characterized by its moderate acidity and stability under normal conditions. Its structure includes a cyclohexane ring with a methyl group at the 2-position and a carboxylic acid functional group. This configuration makes it useful in various chemical reactions, including esterifications and amide formations.
Physical and Chemical Properties
2-Methylcyclohexanecarboxylic acid is a colorless to pale yellow liquid at room temperature. It has a density of approximately 1.0 g/cm³ and a boiling point around 220-230°C. The compound is soluble in common organic solvents such as ethanol and ether but only slightly soluble in water. Its key chemical properties include moderate acidity and stability under normal storage conditions. The presence of the carboxylic acid group allows it to participate in typical acid-base reactions, making it a versatile intermediate in organic synthesis.
Main Applications
The primary use of 2-methylcyclohexanecarboxylic acid is as an intermediate in the pharmaceutical industry. It is involved in the synthesis of various active pharmaceutical ingredients (APIs) and other specialty chemicals. Additionally, it finds applications in the fragrance industry due to its mild odor. In organic synthesis, this compound serves as a building block for more complex molecules. Its reactivity makes it suitable for producing esters, amides, and other derivatives, which are further used in agrochemicals and coatings.
Safety and Storage
2-Methylcyclohexanecarboxylic acid should be handled with care to avoid inhalation or skin contact. Proper personal protective equipment (PPE), including gloves and goggles, is recommended when working with this chemical. It should be used in well-ventilated areas to minimize exposure. Storage conditions should include a cool, dry place away from direct sunlight and oxidizing agents. Containers should be tightly sealed to prevent contamination and degradation. In case of spills, absorb with inert material and dispose of according to local regulations.
B2B Procurement Guide
When procuring 2-methylcyclohexanecarboxylic acid, buyers should verify the CAS number (20448-98-4) and purity specifications to ensure the product meets their requirements. The reference price ranges between $50-$100 per kilogram, depending on purity and order quantity. It is advisable to source from reputable suppliers who provide certificates of analysis (CoA) and material safety data sheets (MSDS). Bulk purchases may attract discounts, but storage capacity and shelf life should be considered to avoid waste.
