Description

5-(2,3-Dimethyltricyclo[2.2.1.02,6]Hept-3-Yl)-2-Methyl-2-Pentenal is a high-value, specialized aldehyde derivative with a complex tricyclic terpene-based structure. This compound matters as a versatile and potent fragrance intermediate and chiral building block for fine chemical synthesis, prized for its unique woody, amber-like olfactory characteristics. It is primarily needed by manufacturers in the flavors and fragrances (F&F) industry, as well as by research and development chemists working on advanced organic synthesis and pharmaceutical intermediates.

Application

• Fragrance Ingredient: A key intermediate in the synthesis of high-value amber, woody, and sandalwood-type fragrance molecules.
• Flavor Modifier: Used in trace amounts to create complex, natural-tasting flavor profiles in premium food and beverage applications.
• Organic Synthesis Building Block: Its reactive aldehyde group and rigid tricyclic framework make it a valuable chiral precursor for pharmaceuticals and agrochemicals.
• Aroma Chemical Research: Serves as a reference standard and starting material in R&D for novel odorants and flavorants.
• Cosmetic Ingredients: Incorporated into high-end perfumes, lotions, and personal care products for its distinctive and long-lasting scent.
• Fine Chemical Intermediate: Used in the multi-step synthesis of complex natural products and specialty chemicals.

Quality Control

Our 5-(2,3-Dimethyltricyclo[2.2.1.02,6]Hept-3-Yl)-2-Methyl-2-Pentenal is produced under strict quality management systems. Every batch undergoes rigorous analytical testing including GC, HPLC, and NMR to ensure high purity, consistent olfactory profile, and chemical identity. Certificates of Analysis (COA) detailing purity, isomer content, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, and open flames.
