Overview
Methyl anthranilate is an ester derived from anthranilic acid, widely recognized for its pleasant grape-like aroma. It is a key ingredient in the flavor and fragrance industries, often used to impart fruity notes to food, beverages, and perfumes. The compound is also employed in industrial applications, such as UV absorbers and insect repellents. First synthesized in the late 19th century, methyl anthranilate has since become a staple in both commercial and industrial settings. Its versatility and relatively low toxicity make it a preferred choice for manufacturers seeking natural-like flavors and fragrances.
Physical and Chemical Properties
Methyl anthranilate is a colorless to pale yellow liquid with a molecular weight of 151.16 g/mol. It has a density of 1.17 g/cm³ and a boiling point of 256-258°C. The compound is soluble in organic solvents like ethanol and ether but only slightly soluble in water. Its fruity odor is attributed to the presence of the amino and ester functional groups. Methyl anthranilate is stable under normal conditions but should be protected from light and oxidizing agents to prevent degradation.
Main Applications
The primary use of methyl anthranilate is as a flavoring agent in food and beverages, particularly in grape-flavored products. It is also a popular fragrance component in perfumes, soaps, and cosmetics due to its pleasant aroma. In industrial applications, methyl anthranilate serves as a UV absorber in plastics and coatings. Additionally, it is used as a bird repellent in agriculture, as birds find its taste and smell unappealing.
Safety and Storage
Methyl anthranilate is generally considered safe for use in food and cosmetics at regulated levels. However, it can cause skin and eye irritation upon direct contact, so proper protective equipment should be worn when handling the chemical. Storage should be in a cool, dry place, away from light and oxidizing agents. Containers must be tightly sealed to prevent contamination and evaporation.
B2B Procurement Guide
When procuring methyl anthranilate, buyers should verify the CAS number (134-20-3) to ensure they are purchasing the correct compound. Purity specifications should align with the intended use, whether for food, fragrance, or industrial applications. It is advisable to source from reputable suppliers who provide certificates of analysis (CoA) and comply with relevant safety and quality standards. Prices vary based on purity and quantity, with bulk purchases often offering cost savings.
