Case 1: Pharmaceutical Synthesis
In a pharmaceutical research project, the goal was to synthesize a new anti - inflammatory drug. 1 - Ethynyl - 1 - Cyclohexanol was used as a key intermediate. First, through an addition reaction with another specific organic compound, a new compound with a more complex structure was formed. The reaction was carried out in an organic solvent at a controlled temperature of 50 - 60 °C for about 3 hours. After the reaction, the product was purified by column chromatography. The final drug product showed good anti - inflammatory effects in preliminary tests.
Case 2: Fragrance Creation
A fragrance company wanted to develop a new perfume with a fresh and unique scent. 1 - Ethynyl - 1 - Cyclohexanol was combined with several other floral and citrus - like fragrance substances. The combination ratio was carefully adjusted. After multiple rounds of testing and optimization, a new perfume with a long - lasting and pleasant scent was created. This perfume was well - received in the market.
