Piperonylic Acid

Updated: 2026-07-22

Overview

Piperonyl acetate is an organic ester derived from piperonyl alcohol and acetic acid. It is widely recognized for its sweet, floral aroma, making it a popular choice in the fragrance and flavoring industries. The compound is often used to enhance floral and heliotrope-like notes in perfumes and as a flavoring agent in food products. Its stability and solubility in organic solvents like alcohol and ether make it versatile for various formulations. Piperonyl acetate is also used in the synthesis of other chemical compounds, further expanding its utility in industrial applications.

Physical and Chemical Properties

Piperonyl acetate is a colorless to pale yellow liquid with a density of approximately 1.19 g/cm³. It has a boiling point ranging between 285-287 °C and is soluble in alcohol and ether but only slightly soluble in water. These properties make it suitable for use in alcoholic solutions and oil-based formulations. The compound exhibits a sweet, floral odor, which is highly valued in perfumery. Its stability under normal storage conditions ensures a long shelf life when stored properly. However, it should be kept away from strong oxidizing agents to prevent decomposition.

Main Applications

Piperonyl acetate is primarily used in the fragrance industry to create floral and heliotrope scents. It is a key ingredient in many perfumes, soaps, and cosmetic products due to its pleasant aroma. In the food industry, it serves as a flavoring agent, often added to candies, baked goods, and beverages to impart a sweet, floral taste. Beyond fragrances and flavors, piperonyl acetate is utilized in the synthesis of other organic compounds. Its chemical properties make it a valuable intermediate in pharmaceutical and agrochemical manufacturing, though these applications are less common compared to its use in perfumery and food additives.

Safety and Storage

While piperonyl acetate is generally considered safe for use in fragrances and flavors, it can cause skin irritation upon direct contact. Proper handling procedures, including the use of gloves and protective clothing, are recommended to minimize exposure. Inhalation of vapors should also be avoided to prevent respiratory irritation. Storage conditions are critical to maintaining the compound's stability. It should be kept in a cool, dry place, away from direct sunlight and moisture. Containers should be tightly sealed to prevent contamination and evaporation. Long-term storage may require nitrogen blanketing to prevent oxidation.

B2B Procurement Guide

When procuring piperonyl acetate, B2B buyers should prioritize suppliers who provide detailed specifications, including CAS number (326-61-4) and purity levels. Verification of these details ensures the product meets industry standards for intended applications. Buyers should also inquire about bulk pricing, as discounts are often available for larger quantities. Quality assurance is another critical factor. Request certificates of analysis (CoA) to confirm the product's purity and composition. Additionally, consider suppliers with a reputation for reliability and timely delivery, especially if the compound is needed for time-sensitive production processes. Sampling before large-scale purchases can help assess quality and suitability.
