Description

Cyclopropylacetaldehyde is a versatile and highly reactive aliphatic aldehyde featuring a cyclopropyl substituent. This unique structure makes it a valuable key intermediate for synthesizing complex molecules in advanced research and development. It is particularly sought after by pharmaceutical and agrochemical industries for constructing novel active ingredients.

Application

• Pharmaceutical Intermediate: A crucial building block for the synthesis of active pharmaceutical ingredients (APIs), especially those requiring the cyclopropane motif for biological activity or metabolic stability.
• Agrochemical Synthesis: Used in the production of advanced pesticides, herbicides, and fungicides where the cyclopropyl group enhances efficacy and environmental profile.
• Flavor & Fragrance Chemistry: Serves as a precursor for creating unique aldehydic and green notes in high-value aroma chemicals.
• Organic Synthesis & Research: A valuable reagent for cyclopropanation reactions, ring-opening transformations, and the construction of complex heterocycles in academic and industrial R&D.
• Material Science Precursor: Employed in the development of specialty polymers and functional materials with tailored properties.

Quality Control

Our Cyclopropylacetaldehyde is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are provided with every shipment 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) in a cool, well-ventilated place. Due to its highly volatile and easily oxidized nature, the container should be kept tightly sealed and away from heat, sparks, and open flames. Recommended storage temperature is 2-8°C for long-term stability.
