1-Nonanal丨CAS 124-19-6

1-Nonanal丨CAS 124-19-6 is a linear aliphatic aldehyde composed of a nine-carbon straight chain with a terminal aldehyde group. Naturally occurring in various essential oils and plant extracts, it is widely used across flavor, fragrance, pharmaceutical, and industrial sectors.

1. Fragrance and Perfume Industry
1-Nonanal丨CAS 124-19-6 is extensively used in the formulation of perfumes and scented products due to its pleasant, rich, and long-lasting aroma:
● Imparts a fresh, citrusy, and floral note, often compared to rose, orange peel, or green leafy tones.
● Commonly found in:
oFine perfumes
oSoaps and detergents
oCosmetics
oAir fresheners
oCandles
As a middle to top note, it adds vibrancy and a natural freshness to complex fragrance blends.

2. Flavoring Agent
In the food and beverage industry, 1-Nonanal is used as a flavoring additive:
● Found naturally in citrus oils, oranges, lemons, mandarins, and green vegetables.
● Used in trace amounts to add a fresh, waxy citrus peel or herbal character to processed foods, beverages, and baked goods.
● Approved by the Flavor and Extract Manufacturers Association (FEMA #2790) and other international bodies for food use in very low concentrations.

3. Pheromones and Insect Attractants
1-Nonanal丨CAS 124-19-6 has been identified as a semiochemical, playing roles in insect behavior:
● Acts as an attractant or repellent depending on the insect species.
● Used in pest monitoring and control systems in agriculture and entomology research.
● For example, it has been shown to influence the behavior of mosquitoes, making it a candidate for repellent formulations or bait systems in vector control.

4. Pharmaceutical and Biomedical Research
While not directly used as a therapeutic drug, 1-Nonanal has notable applications in biomedical research:
● Studied as a biomarker for diseases due to its presence in human exhaled breath or body odor, especially in:
oLung cancer
oSkin conditions
oMetabolic disorders
This makes it useful in non-invasive diagnostic technologies and the development of electronic nose (e-nose) sensors.

5. Industrial and Chemical Synthesis
As an intermediate in organic synthesis, 1-Nonanal is used for:
● Producing long-chain alcohols, acids, and esters.
● Manufacturing of nonionic surfactants, plasticizers, and lubricants.
● Acts as a building block for more complex aromatic compounds in industrial chemistry.

1. Natural and Pleasant Aroma
1-Nonanal丨CAS 124-19-6 offers a clean, natural fragrance with green and citrusy qualities:
● Enhances product appeal in cosmetics, personal care, and cleaning products.
● Compatible with both natural and synthetic fragrance systems, allowing for versatile use.
2. Enhances Flavor Profiles
● Even in minute concentrations, 1-Nonanal enhances flavor complexity in food and drink products.
● Its fatty, citrusy notes make it ideal for citrus-themed or savory flavor blends, improving organoleptic perception.
3. Bio-Based and Sustainable
● Naturally derived from plant essential oils, especially citrus peels and rose oil, making it a sustainable and eco-friendly ingredient.
● Offers a natural alternative to synthetic aroma compounds in green formulations.
4. Functional in Pest Control
● Its role in mosquito behavior modulation makes it an attractive component in insect control solutions, particularly as a non-toxic alternative to harsh pesticides.
5. Research Relevance
● Serves as a volatile organic compound (VOC) of interest in studies of air quality, disease diagnostics, and sensor technology.
● Its detectability in exhaled breath and skin emissions adds to its significance in health monitoring and biometrics.

Conclusion
1-Nonanal丨CAS 124-19-6 is a versatile and naturally occurring aldehyde valued for its fragrant, flavor-enhancing, and semiochemical properties. It finds widespread application in the fragrance, flavor, pharmaceutical research, agriculture, and chemical synthesis industries.
