trans-4-Methoxycyclohexanecarboxylic acid(CAS: 73873-61-7)

Trans-4-Methoxycyclohexanecarboxylic acid is a colorless solid with a molecular weight of approximately 166.17 g/mol. It has a melting point of 71-73°C and a solubility of 0.8 g/L in water. It is moderately reactive, particularly in acidic conditions, and can form esters and anhydrides. It is insoluble in most organic solvents but soluble in water and polar solvents.

Trans-4-Methoxycyclohexanecarboxylic acid is typically synthesized by the methylation of cyclohexanecarboxylic acid using methanol and an acid catalyst such as sulfuric acid. The reaction is carried out under mild conditions, and the desired trans isomer can be obtained with high selectivity. The yield is generally around 75-85%.

Trans-4-Methoxycyclohexanecarboxylic acid is used in the pharmaceutical industry as a precursor for drug synthesis, in the polymer industry for the production of functionalized polymers, and in the sensor industry for the development of gas-sensitive materials. It is also used in the semiconductor industry for photolithography processes.

When handling trans-4-Methoxycyclohexanecarboxylic acid, it is important to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood. Spills should be cleaned up using appropriate absorbent materials, and the area should be ventilated. It is advisable to consult the Safety Data Sheet (SDS) for detailed safety information and emergency procedures.
