Citronellal, also identified by its synonym Rhodinal and CAS number 106-23-0, is a compound of significant interest in the chemical industry, particularly within the realms of fragrance and flavor. Understanding its citronellal chemical properties is paramount for formulators and manufacturers aiming to achieve specific scent and taste profiles in their products. This article aims to provide a comprehensive look at what makes Citronellal such a valuable ingredient.

The physical appearance of Citronellal is typically described as a light yellow to yellow clear liquid. Its odor is a defining characteristic – a strong, sweet grass aroma that makes it highly recognizable and sought after. Beyond its scent, its citronellal typical properties include a specific gravity usually between 0.888 and 0.892 and a refractive index ranging from 1.470 to 1.474. These parameters are crucial for quality control and ensuring the consistency of the ingredient.

One of the most critical aspects of Citronellal is its utility in synthesis. It serves as a primary raw material for producing other important aroma chemicals, most notably citronellol and hydroxycitronellal. These derivatives are foundational in creating various floral notes, especially rose and lily of the valley, which are indispensable in modern perfumery. The citronellal uses in perfumery are therefore expansive, contributing to both the creation of new scents and the refinement of existing ones.

Furthermore, Citronellal is extensively employed as a flavoring agent. Its characteristic aroma translates well into taste, lending a rich lemon or lemongrass note to beverages, candies, and other food items. This dual application in both scent and flavor highlights its versatility.

The insect-repellent properties of Citronellal also warrant significant attention. It is a well-known component in many insect repellent formulations, offering a natural and effective solution for pest control. This makes it an attractive ingredient for companies developing eco-friendly and consumer-safe products.

The citronellal synthesis can be achieved through various chemical routes or by extracting it from natural sources, such as citronella oil. The precise CAS number, 106-23-0, ensures the correct identification of this specific chemical entity. The quality and purity of the Citronellal used are directly linked to the performance and safety of the final products, whether they are perfumes, flavors, or repellents.

For industries reliant on high-quality aroma chemicals, partnering with a reliable supplier like NINGBO INNO PHARMCHEM CO.,LTD. is essential. They ensure that the Citronellal provided meets rigorous standards, facilitating successful product development and manufacturing processes. By leveraging the unique properties of Citronellal, businesses can create products that are both sensorially pleasing and functionally effective.
