Overview
3-Methoxycinnamic Acid is an organic compound derived from cinnamic acid, featuring a methoxy group at the meta position of the phenyl ring. It is commonly used in the synthesis of fragrances, pharmaceuticals, and UV-absorbing agents. The compound is recognized for its aromatic properties and stability, making it a valuable intermediate in various chemical processes. In industrial settings, 3-Methoxycinnamic Acid is often sourced in crystalline powder form, ensuring ease of handling and storage. Its applications span across multiple industries, including cosmetics, where it serves as a key ingredient in sunscreens due to its UV-absorbing capabilities.
Physical and Chemical Properties
3-Methoxycinnamic Acid is characterized by its white to off-white crystalline appearance and a molecular weight of 178.18 g/mol. It has a melting point of approximately 130-132°C, which makes it stable under normal processing conditions. The compound is soluble in common organic solvents like ethanol and acetone but has limited solubility in water. One of its notable chemical properties is its ability to absorb UV light, which is why it is frequently used in sunscreen formulations. The methoxy group enhances its stability and reactivity, making it suitable for further chemical modifications in synthetic applications.
Main Applications
The primary use of 3-Methoxycinnamic Acid is as an intermediate in the pharmaceutical industry, where it is involved in the synthesis of various active pharmaceutical ingredients (APIs). It is also a key component in the fragrance industry, contributing to the production of aromatic compounds. In cosmetics, this compound is valued for its UV-absorbing properties, making it a common ingredient in sunscreens and other skincare products designed to protect against harmful ultraviolet radiation. Additionally, it is used in organic synthesis to create derivatives with enhanced functionalities.
Safety and Storage
When handling 3-Methoxycinnamic Acid, it is essential to follow standard safety protocols to minimize exposure. The compound should be stored in a cool, dry environment, away from direct sunlight and moisture, to maintain its stability. Proper labeling and secure containers are recommended to prevent accidental ingestion or inhalation. Personal protective equipment (PPE), such as gloves and goggles, should be worn during handling to avoid skin and eye contact. In case of exposure, rinse thoroughly with water and seek medical attention if necessary. Always refer to the Material Safety Data Sheet (MSDS) for detailed safety information.
B2B Procurement Guide
When procuring 3-Methoxycinnamic Acid, it is crucial to verify the CAS number (6099-03-2) and purity specifications to ensure you receive the correct product. Request a Certificate of Analysis (COA) and MSDS from suppliers to confirm quality and safety standards. Prices typically range between $50 and $100 per kilogram, depending on purity and supplier reliability. Bulk purchases may offer cost savings, but always assess supplier credibility and delivery timelines. Consider working with established chemical distributors to mitigate risks associated with quality and consistency.
