Description

trans-2-Pentenal is an alpha,β-unsaturated aldehyde characterized by its distinct, pungent aroma. This compound serves as a versatile intermediate and flavor/fragrance component due to its reactive carbonyl and alkene functionalities. It is primarily utilized by manufacturers in the flavor & fragrance, agrochemical, and pharmaceutical synthesis industries.

Application

• Flavor and Fragrance Ingredient: Used as a key component in creating green, fruity, and nutty flavor profiles for food products and fragrance compositions.
• Chemical Synthesis Intermediate: Acts as a crucial building block in organic synthesis, particularly in aldol condensations and Michael addition reactions.
• Agrochemical Synthesis: Employed in the production of certain pesticides and herbicides as a precursor molecule.
• Pharmaceutical Research: Serves as a starting material or intermediate in the synthesis of more complex bioactive molecules and active pharmaceutical ingredients (APIs).
• Polymer Chemistry: Can be used as a monomer or cross-linking agent in specialty polymer formulations.
• Analytical Reference Standard: Supplied as a high-purity standard for gas chromatography (GC) and mass spectrometry (MS) analysis in quality control laboratories.

Quality Control

Our trans-2-Pentenal is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC assay and identity confirmation (IR), to ensure it meets the required purity and specification standards. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and batch-to-batch consistency.

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.
