Description

Isopropyl (E)-p-Methoxycinnamate is a high-purity organic ester compound, widely recognized for its role as a key intermediate and active ingredient. Its primary commercial value lies in its ability to absorb specific wavelengths of ultraviolet light, making it a critical component for advanced formulations. This product is essential for manufacturers in the cosmetics, personal care, and pharmaceutical industries seeking reliable, high-quality UV filters and synthesis building blocks.

Application

• Primary UV Filter in Sunscreen Formulations: Used in sunscreens, day creams, and after-sun products for its effective absorption of UV-A and UV-B radiation.
• Photostabilizer in Cosmetic Products: Incorporated into lipsticks, foundations, and other color cosmetics to protect the formulation and pigments from photo-degradation.
• Intermediate for Pharmaceutical Synthesis: Serves as a key building block in the synthesis of more complex organic molecules with potential biological activity.
• Additive in Polymer Coatings: Used to enhance the UV resistance and longevity of specialty paints, varnishes, and plastic coatings.
• Fragrance and Flavor Ingredient Intermediate: Employed in the synthesis of certain aroma chemicals due to its cinnamate structure.

Quality Control

Our Isopropyl (E)-p-Methoxycinnamate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and compliance with relevant specifications. Certificates of Analysis (COA) documenting assay, isomer purity, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). This material is light-sensitive and easily oxidized; for long-term storage, consider an inert atmosphere (e.g., nitrogen or argon blanket) to maintain optimal stability and prevent degradation.
