ethylene inhibitor (1-MCP) 1-methylcyclopropeneCAS: 3100-04-7 Assay: >4.3% 

1-MCP is a cycloalkene with the molecular formula C4H6. It is a volatile gas at standard temperature and pressure with a boiling point of ~12 °C1-Methylcyclopropene (1-MCP) is a cyclopropene derivative used as a synthetic plant growth regulator. It is structurally related to the natural plant hormone ethylene and it is used commercially to slow down the ripening of fruit and to help maintain the freshness of cut flowers.Mechanism of action:Ethylene exists as a gas and it acts at trace levels throughout the life of a plant by stimulating or regulating various processes such as the ripening of fruit, the opening of flowers, and the shedding of leaves. The mechanism of action of 1-MCP involves it tightly binding to the ethylene receptor in plants and thereby blocking the effects of ethylene.Commercial use:There are two principal commercial uses of 1-MCP: maintaining the freshness of ornamental plants and flowers, and preventing the ripening of fruits. In each case, 1-MCP is combined with other materials for handling and then mixed with a specific amount of water or other solution to release it into the air. It is used in enclosed indoor sites, such as coolers, truck trailers, greenhouses, storage facilities, and shipping containers.Under the brand name EthylBloc, 1-MCP was approved by the U.S. Environmental Protection Agency for use on ornamental crops. It is used with cut flowers, potted flowers, and bedding, nursery and foliage plants to prevent premature wilting, leaf yellowing, premature opening, and premature death.
