Description

Caproic Acid Propyl Ester is a clear, colorless liquid ester known for its fruity, pineapple-like aroma and highly volatile nature. This compound serves as a versatile intermediate and flavor/fragrance component, valued for its ability to impart specific organoleptic qualities and act as a solvent or reaction medium. It is primarily sought after by manufacturers in the flavor & fragrance, food processing, and specialty chemical synthesis industries.

Application

• Flavor & Fragrance Agent: Used as a key aromatic component in creating fruity, pineapple, and tropical notes for perfumes, cosmetics, and food flavorings.
• Food Additive: Employed as a synthetic flavoring substance in processed foods, beverages, and confectionery.
• Chemical Intermediate: Acts as a building block in organic synthesis for pharmaceuticals, agrochemicals, and other fine chemicals.
• Solvent & Extraction Medium: Utilized in specialized extraction processes and as a solvent for resins, oils, and other organic compounds.
• Plasticizer Precursor: Can be used in the production of certain plasticizers and polymer additives.
• Research & Development: Serves as a reagent and standard in analytical chemistry and R&D laboratories.

Quality Control

Our Caproic Acid Propyl Ester is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) detailing key parameters such as assay, odor, appearance, and specific gravity, confirming compliance with relevant standards like FCC (Food Chemicals Codex) for flavor grade applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain quality. Recommended storage temperature is 15-25°C.
