Description

(+)-Citronellal CAS NO 2385-77-5 is a high-purity, naturally derived monoterpenoid aldehyde prized for its characteristic fresh, citrus-like aroma. This compound serves as a critical chiral building block and fragrance ingredient, offering significant value in fine chemical synthesis and flavor & fragrance formulation. It is essential for manufacturers in the perfumery, flavoring, and pharmaceutical intermediates sectors seeking a reliable, high-quality source of this specific enantiomer.

Application

• Fragrance & Flavor Industry: A key ingredient in fine perfumery for citrus, floral, and herbal accords, and used as a flavoring agent in food and beverages.
• Pharmaceutical Intermediates: Serves as a chiral starting material for the synthesis of active pharmaceutical ingredients (APIs) and vitamins, such as (-)-menthol.
• Agrochemicals: Used in the production of insect repellents and as an intermediate for certain pesticides and pheromones.
• Household & Industrial Products: Incorporated into air fresheners, detergents, cleaning agents, and personal care products for its fresh scent and antimicrobial properties.
• Chemical Synthesis: A versatile intermediate in organic chemistry for cyclization reactions and the synthesis of other terpenoids and fine chemicals.

Quality Control

Our (+)-Citronellal is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure it meets stringent specifications for identity, purity, and enantiomeric excess. A comprehensive Certificate of Analysis (COA) detailing assay, optical rotation, and impurity profiles is provided with every shipment. We can supply material compliant with FCC, ISO, and other relevant standards for food, fragrance, and pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep container tightly sealed when not in use to prevent evaporation and oxidation.
