Delayed release is important for several reasons: 1. Optimization of Reaction Conditions: It allows for the reaction to occur under optimal conditions, thus improving the efficiency and selectivity of the catalytic process. 2. Controlled Reaction Rates: It helps in controlling the rate of reaction, preventing undesirable side reactions and ensuring the desired product yield. 3. Safety and Stability: In many cases, catalysts or reactants may be unstable or hazardous. Delayed release can enhance safety and stability by ensuring the catalyst is only active when needed.
