Overview
Methyl cinnamate is an ester derived from cinnamic acid and methanol, widely recognized for its pleasant, fruity aroma. It is naturally present in essential oils such as basil and cinnamon but is predominantly synthesized for industrial use. The compound is a key ingredient in the fragrance and flavor industries due to its stability and versatile scent profile. In addition to its olfactory applications, methyl cinnamate serves as an intermediate in organic synthesis. Its ability to undergo reactions like hydrogenation and esterification makes it valuable for producing pharmaceuticals and specialty chemicals. The compound's low toxicity and biodegradability further enhance its appeal in sustainable manufacturing processes.
Physical and Chemical Properties
Methyl cinnamate is a colorless to pale yellow liquid with a characteristic sweet, balsamic odor reminiscent of strawberries. It has a molecular weight of 162.19 g/mol and a density of 1.092 g/cm³. The compound melts at 34-38 °C and boils at 260-262 °C, exhibiting moderate volatility. Its solubility profile includes miscibility with organic solvents like ethanol and ether but limited solubility in water. Methyl cinnamate is stable under normal conditions but may decompose upon exposure to strong oxidizing agents. Its flammability requires careful handling and storage away from ignition sources.
Main Applications
The primary use of methyl cinnamate is in the fragrance industry, where it imparts sweet, fruity notes to perfumes, soaps, and cosmetics. It is also a popular food flavoring agent, enhancing products like candies, baked goods, and beverages with its strawberry-like aroma. In pharmaceuticals, methyl cinnamate acts as a precursor for synthesizing anti-inflammatory and antimicrobial compounds. Its role in organic synthesis extends to producing UV absorbers and plasticizers. The compound's versatility and low environmental impact make it a preferred choice for eco-conscious formulations.
Safety and Storage
Methyl cinnamate poses moderate health risks, including irritation to the skin, eyes, and respiratory system. Proper personal protective equipment (PPE), such as gloves and goggles, is essential during handling. Inhalation or ingestion should be avoided, and affected areas must be rinsed thoroughly with water. Storage recommendations include keeping the compound in a cool, dry, well-ventilated area, away from heat sources and open flames. Containers should be tightly sealed to prevent moisture absorption and oxidation. Spills should be contained using inert absorbents and disposed of according to local regulations.
B2B Procurement Guide
When procuring methyl cinnamate, B2B buyers should prioritize suppliers with certifications like ISO or GMP to ensure product quality. Key specifications to verify include CAS number (103-26-4), purity (typically 98-99%), and absence of contaminants. Bulk purchases often attract discounts, but buyers should assess storage capabilities to prevent degradation. Sample testing is advisable to confirm suitability for specific applications. Transparent logistics and compliance with international shipping regulations are critical for seamless procurement.
