Ru-MACHO should be stored in a cool, dry place away from direct sunlight and sources of heat. It is recommended to use airtight containers to prevent exposure to moisture and air, which may affect its stability. Due to the presence of toluene, it should be handled with care, using appropriate personal protective equipment such as gloves and safety goggles. The material is not flammable but should be kept away from incompatible substances. Regular inspection of storage conditions is advised to ensure the integrity of the compound. Proper labeling and storage practices are essential to maintain safety and effectiveness in laboratory environments.
