Description

3-Cyclopropylpropanal is a versatile aliphatic aldehyde building block characterized by its reactive carbonyl group and unique cyclopropyl moiety. This compound matters for its role as a key chiral intermediate in the synthesis of complex molecules, offering a pathway to introduce cyclopropane rings, which are valuable structural motifs in bioactive compounds. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and fragrance industries for constructing novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those containing cyclopropane rings for enhanced metabolic stability and biological activity.
• Agrochemical Synthesis: Used in the development of novel pesticides and herbicides, where the cyclopropyl group can contribute to specific modes of action and environmental profiles.
• Flavor & Fragrance Ingredient: Serves as a building block for creating unique aldehydic and green olfactory notes in high-value perfumery and flavor compositions.
• Organic Synthesis Reagent: Employed in various name reactions, including Wittig olefination, reductive amination, and Grignard additions, to extend carbon chains and introduce functional groups.
• Material Science Research: Investigated as a monomer or cross-linking agent in the development of specialty polymers with tailored properties.
• Chemical Biology Probe: Utilized in the design and synthesis of molecular probes to study enzyme mechanisms and biological pathways.

Quality Control

Our 3-Cyclopropylpropanal is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (GC/HPLC) and spectroscopy (IR, NMR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) in a cool (15-25°C), well-ventilated area, away from heat and ignition sources. Due to its highly volatile and easily oxidized nature, containers must be kept tightly sealed and should be allowed to reach room temperature before opening to minimize moisture ingress and degradation.
