Synonym: Epa pesticide chemical code 224459; Ethylbloc; Hsdb 7517; Smartfresh; 1-Methylcyclopropene,1-MCP; 1-mcp powder; Cyclopropene, 1-methyl-; 1-Methylcyclopropene; 1-Methylcyclopropen
1-Methylcyclopropene (1-MCP) is a highly effective and safe plant growth regulator widely recognized around the world. It is mainly used in the post-harvest preservation of fruits, vegetables, and flowers. By slowing down the natural ripening and aging process, 1-MCP helps maintain freshness, flavor, and texture, while significantly extending shelf life.
Today, 1-MCP has become a key technology in the storage, transport, and sale of fresh produce, especially for apples, pears, bananas, kiwifruit, and cut flowers.

Delays ripening and aging – prevents fruits and vegetables from softening, yellowing, or losing flavor.
Maintains texture – keeps apples, pears, and other fruits firm and crisp, avoiding post-harvest mealiness.
Reduces disease incidence – slows physiological decline, lowering the chance of decay and spoilage.
Preserves color and taste – keeps produce vibrant and flavorful by inhibiting chlorophyll breakdown.
1-MCP is widely applied across different categories of produce:
Pome fruits: Apples, pears – standard in storage facilities to preserve quality for months.
Tropical fruits: Bananas, kiwifruit, mangoes, papayas – controls ripening for transport and export.
Citrus fruits: Reduces peel disorders such as puffiness and shriveling.
Vegetables: Tomatoes, bell peppers, broccoli, leafy greens – slows softening and yellowing.
Flowers & ornamentals: Carnations, lilies, roses, and potted plants – delays wilting, petal drop, and leaf yellowing, extending vase and shelf life.
When fruits and vegetables ripen, they release ethylene gas, a natural plant hormone that triggers aging.
1-MCP works by:
Binding to the ethylene receptors inside plant cells.
Blocking ethylene’s ability to start the ripening process.
“Pausing” the natural aging process without harming the produce.
This simple but powerful mechanism allows growers, distributors, and retailers to control freshness with precision.
1. Purity: The industry standard is 3.3%, and we can achieve 3.7%.
2. We offer microdosing, with small packages of 0.035% for use on supermarket shelves or in fruit boxes.
3. Product safety: 1-MCP is a gas molecule that dissipates completely after processing, leaving no chemical residue on the product.

Q: What is CAS 3100-04-7? How does it work?
A: 1-MCP is a competitive inhibitor of ethylene receptors. Ethylene is a hormone that triggers the aging process in fruits and vegetables; 1-MCP irreversibly binds to plant ethylene receptors, blocking the ethylene signal, delaying fruit ripening, softening, discoloration, and decay, and extending the shelf life of preservation; it does not kill bacteria and is a physiological preservation method, not a fungicide.
Q: What is the appearance and common specifications of the product?
A: Marketed powder form: white powder; common effective component 1-MCP: 3.5% WP
Packaging: 1g / 5g small bags; 1kg, 25kg barrels / bags.
Q: Which fruits and vegetables / flowers are suitable for use? Which ones are not recommended?
A: Recommended for ethylene-sensitive fruits and vegetables such as apples, kiwis, pears, avocados, persimmons, broccoli, roses, lilies, etc.
Q: Storage conditions? Stability?
A: Store in a sealed, cool, dry, and dark place. It is recommended to refrigerate at 2–8℃; avoid high temperatures and humidity. Exposure to moisture will cause 1-MCP gas to be released prematurely, leading to the degradation of the effective component; keep away from open flames. The shelf life of powder form is generally 2 years under sealed conditions.
Q: What is the minimum order quantity (MOQ)?
A: Regular batch orders MOQ: 1kg. Small packaging options: 1g / bag, 5g / bag, 10g / bag, 100g aluminum foil bag; Large packaging: 1kg / barrel, 25kg / barrel. Custom packaging (custom labels, aluminum foil bag printing, custom packaging has a minimum order requirement) is acceptable.
Q: How long is the shipping lead time (Lead time)?
A: Regular specifications: Payment confirmation followed by 1–3 working days for order arrangement; Custom packaging / special formula orders: 5–7 working days.
