Description

Heptanal CAS NO 111-71-7 is a seven-carbon aliphatic aldehyde, also known as heptyl aldehyde or enanthaldehyde. This compound serves as a versatile intermediate and a key fragrance ingredient, valued for its characteristic fatty, citrus-like odor. It is essential for manufacturers in the flavors & fragrances, agrochemical, and pharmaceutical industries seeking to synthesize complex molecules or impart specific organoleptic properties.

Application

• Fragrance and Flavor Ingredient: Used as a key component in creating citrus, fatty, and green notes for perfumes, cosmetics, and food flavorings.
• Chemical Synthesis Intermediate: A crucial building block for producing alcohols (e.g., heptanol), acids, and other derivatives like heptanoic acid.
• Agrochemical Production: Serves as a precursor in the synthesis of certain pesticides, herbicides, and plant growth regulators.
• Pharmaceutical Intermediates: Utilized in the synthesis of active pharmaceutical ingredients (APIs) and other fine chemicals.
• Plasticizer and Polymer Additive: Employed in the manufacture of plasticizers and as a modifier in polymer formulations.
• Organic Synthesis Reagent: Used in various organic reactions, including aldol condensations and reductive amination, for research and development.

Quality Control

Our Heptanal is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets exacting standards for industrial and specialty applications. Certificates of Analysis (COA) documenting all relevant specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents, strong bases, and strong reducing agents. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize headspace. Recommended storage temperature: 2-8°C.
