Description

trans-Citral, also known as trans-3,7-Dimethyl-Octa-2,6-Dien-1-Al, is a key isomer of the naturally occurring monoterpene aldehyde citral. It is prized for its intense, fresh lemon-like aroma and flavor, making it an indispensable ingredient in fragrance and flavor creation. This high-purity compound is essential for manufacturers in the flavor & fragrance, food & beverage, and personal care industries seeking consistent quality and reliable supply.

Application

• Flavor & Fragrance Formulation: A primary building block for creating fresh, citrus, and lemon top notes in perfumes, colognes, air fresheners, and household products.
• Food & Beverage Flavoring: Used as a key flavor component in beverages, confectionery, baked goods, and dairy products to impart a natural citrus character.
• Aroma Chemical Synthesis: Serves as a crucial intermediate in the industrial synthesis of other valuable aroma chemicals like ionones (for violet scent) and vitamins (Vitamin A and E).
• Personal Care & Cosmetics: Incorporated into soaps, shampoos, lotions, and creams for its refreshing scent and masking properties.
• Household & Industrial Products: Adds a pleasant lemon fragrance to cleaning agents, detergents, and other functional products.
• Research & Development: Utilized in analytical laboratories and R&D facilities as a reference standard and for chemical studies.

Quality Control

Our trans-Citral is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. We offer grades suitable for flavor, fragrance, and technical applications, with specifications meeting industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, isomer content, and physical parameters is provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, an inert atmosphere (e.g., nitrogen) is recommended to maintain optimal quality and stability.
