Overview
Dihydrocinnamaldehyde, chemically known as 3-phenylpropanal, is an aromatic aldehyde with a floral, cinnamon-like scent. It is widely utilized in the fragrance and flavor industries due to its pleasant odor profile. This compound is also a valuable intermediate in organic synthesis, particularly in the production of pharmaceuticals and fine chemicals. Its natural occurrence is rare, but it can be derived through the hydrogenation of cinnamaldehyde or synthesized via other organic pathways. The compound's stability and versatility make it a preferred choice for various industrial applications.
Physical and Chemical Properties
Dihydrocinnamaldehyde is a colorless to pale yellow liquid with a characteristic sweet, floral aroma. It has a molecular weight of 134.18 g/mol and a density of 1.02 g/cm³. The compound's boiling point ranges between 221-222°C, and it is slightly soluble in water but miscible with alcohol and ether. Its chemical stability under normal conditions makes it suitable for long-term storage, provided it is kept away from oxidizing agents and heat sources. The aldehyde functional group in its structure allows it to participate in various chemical reactions, including reductions and condensations.
Main Applications
The primary use of dihydrocinnamaldehyde is in the fragrance industry, where it serves as a key ingredient in perfumes, soaps, and cosmetics. Its cinnamon-like scent enhances floral and spicy notes in formulations. Additionally, it is employed in the flavor industry to impart sweet, aromatic profiles to food products. In pharmaceuticals, dihydrocinnamaldehyde acts as an intermediate in the synthesis of active pharmaceutical ingredients (APIs). Its role in organic synthesis extends to the production of dyes, resins, and other specialty chemicals.
Safety and Storage
Dihydrocinnamaldehyde should be handled with care to avoid skin and eye irritation. Proper personal protective equipment (PPE), such as gloves and goggles, is recommended during use. In case of contact, rinse thoroughly with water and seek medical advice if irritation persists. Storage conditions should include a cool, dry, and well-ventilated area, away from direct sunlight and ignition sources. The compound should be kept in tightly sealed containers to prevent contamination and evaporation.
B2B Procurement Guide
When procuring dihydrocinnamaldehyde, buyers should prioritize suppliers with verified certifications (e.g., ISO, GMP) to ensure product quality and regulatory compliance. Key factors to consider include purity levels (typically 98-99%), packaging options, and batch consistency. Price negotiations should account for order volume, with bulk purchases often yielding discounts. Additionally, buyers should confirm lead times and shipping conditions to avoid delays or product degradation during transit.
