Description

2,3-Dimethyl-4-(2,6,6-Trimethyl-1-Cyclohexen-1-Yl)-2-Butenal is a high-value, unsaturated aldehyde derivative of β-ionone, serving as a key intermediate in the synthesis of complex organic molecules. Its structure makes it a versatile building block for creating specific fragrance and flavor notes, as well as advanced pharmaceutical compounds. This product is essential for R&D chemists and production specialists in the flavor & fragrance, fine chemical, and life sciences industries seeking to develop or manufacture sophisticated aroma chemicals and active ingredients.

Application

• Fragrance & Flavor Industry: A critical intermediate for synthesizing high-value aroma chemicals, particularly those with woody, amber, or floral notes derived from ionone and damascone families.
• Fine Chemical Synthesis: Used as a specialized building block in multi-step organic synthesis for creating complex natural product analogs and other advanced chemical entities.
• Pharmaceutical Intermediates: Serves as a precursor in the research and development of novel active pharmaceutical ingredients (APIs), especially those with terpenoid or carotenoid-based structures.
• Vitamin A & Carotenoid Synthesis: Acts as a key chiral intermediate in the synthetic pathways for vitamins (e.g., Vitamin A) and carotenoid pigments.
• Agrochemical Research: Utilized in developing new generation plant growth regulators or bioactive agrochemicals due to its structural similarity to natural plant hormones.
• Specialty Polymer Additives: Investigated for use in creating functional monomers that impart specific olfactory or UV-stabilizing properties to polymers.

Quality Control

Our 2,3-Dimethyl-4-(2,6,6-Trimethyl-1-Cyclohexen-1-Yl)-2-Butenal is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC/HPLC for purity and identity confirmation (IR, NMR), to ensure it meets exacting standards for research and industrial use. Certificates of Analysis (COA) documenting batch-specific results are provided to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (15-25°C). This material is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep away from heat, sparks, and open flame.
