At NINGBO INNO PHARMCHEM CO.,LTD., we are dedicated to providing insights into the chemistry behind essential industrial compounds. Today, we focus on Nonanal (CAS 124-19-6), also known as Aldehyde C-9, examining its synthesis, properties, and diverse industrial applications.

Nonanal is classified as a medium-chain aldehyde, a group of organic compounds characterized by their carbonyl group. Its chemical formula is C9H18O, and its structure is a linear chain of nine carbon atoms with an aldehyde functional group at one end. Industrially, Nonanal is commonly produced through the hydroformylation of 1-octene. This process, also known as the 'oxo' process, involves reacting an alkene with synthesis gas (a mixture of carbon monoxide and hydrogen) in the presence of a catalyst, typically a rhodium or cobalt complex, to yield aldehydes.

The chemical synthesis of Nonanal ensures a consistent and high-purity product for various applications. Its key properties include its appearance as a clear, colorless to light yellow liquid, a melting point of -18°C, and a boiling point of approximately 191°C at atmospheric pressure. Nonanal is sparingly soluble in water but readily soluble in organic solvents like ethanol and ethyl acetate, which is crucial for its use in fragrance and flavor formulations.

While Nonanal is widely recognized for its significant role in the fragrance industry, imparting waxy, citrus, and green notes, its applications extend further. In the flavor industry, it serves as a food additive, enhancing citrus notes, particularly lemon and mandarin. Its presence in functional perfumery, such as in detergents and soaps, adds a pleasant scent to everyday products. Furthermore, Nonanal has been identified in various biological contexts, including as a plant metabolite and even as a compound that attracts mosquitoes, suggesting potential applications in agricultural research or pest control.

The properties of Nonanal aldehyde, such as its distinct odor and chemical reactivity, make it a valuable intermediate in the synthesis of other chemicals. It can be oxidized to nonanoic acid or reduced to nonanol, opening pathways for further chemical modifications.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to supplying high-quality Nonanal that meets the rigorous demands of various industries. Understanding the synthesis and diverse applications of this vital compound allows us to better serve our clients in their product development and manufacturing processes.

In conclusion, Nonanal is a prime example of a fundamental chemical compound with far-reaching industrial significance. Its efficient synthesis and versatile properties ensure its continued importance across perfumery, food flavoring, and beyond.
