Description

3-(3,3-Dimethylbicyclo[2.2.1]Hept-5-En-2-Yl)-2-Butenal is a specialized bicyclic terpenoid aldehyde with a unique structural framework. This compound matters as a high-value intermediate for synthesizing complex fragrance molecules and fine chemicals, offering a distinct woody, amber-like olfactory character. It is primarily needed by manufacturers in the fragrance and flavor industry, as well as by research chemists developing novel organic compounds and chiral catalysts.

Application

• Fragrance & Flavor Industry: A key building block for creating sophisticated amber, woody, and sandalwood-type fragrance accords in perfumes, cosmetics, and personal care products.
• Fine Chemical Synthesis: Serves as a versatile chiral intermediate in the multi-step synthesis of complex natural products, pharmaceuticals, and agrochemicals.
• Organic Research & Development: Used in academic and industrial R&D for studying Diels-Alder reactions and other cycloaddition chemistry due to its strained bicyclic structure.
• Specialty Polymer Modifiers: Potential application as a monomer or cross-linking agent for introducing rigid, hydrophobic character into specialty polymers and resins.

Quality Control

Our 3-(3,3-Dimethylbicyclo[2.2.1]Hept-5-En-2-Yl)-2-Butenal is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistent isomeric composition. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C for long-term stability. Allow the container to reach ambient temperature before opening to minimize moisture ingress.
