Description

Para-Propionaldehyde is a specialized organic compound, also known as 3-Phenylpropionaldehyde, with the CAS registry number 2396-42-1. This aromatic aldehyde serves as a versatile and valuable intermediate in fine chemical synthesis, prized for its ability to introduce the phenylpropyl moiety into target molecules. It is essential for manufacturers and R&D laboratories in the fragrance, pharmaceutical, and agrochemical sectors seeking to develop new products or enhance existing synthetic routes.

Application

• Fragrance and Flavor Ingredient: A key building block for synthesizing aromatic compounds used in perfumes, cosmetics, and food flavorings due to its characteristic balsamic, hyacinth-like odor.
• Pharmaceutical Intermediate: Employed in the synthesis of active pharmaceutical ingredients (APIs) and other bioactive molecules, particularly those requiring a phenylpropyl functional group.
• Agrochemical Synthesis: Used as a precursor in the production of certain pesticides, herbicides, and plant growth regulators.
• Organic Synthesis Reagent: A valuable reagent in various organic transformations, including Grignard reactions, reductions, and condensations, to construct more complex chemical architectures.
• Research & Development: Utilized in academic and industrial R&D for exploring new synthetic methodologies and developing novel chemical entities.

Quality Control

Our Para-Propionaldehyde is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including Gas Chromatography (GC) and Infrared Spectroscopy (IR), to verify identity and assay. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents, strong bases, and strong reducing agents. Recommended storage temperature is 2-8°C for long-term stability. The compound is hygroscopic and should be handled under an inert atmosphere to prevent oxidation and moisture absorption.
