Ecamsule(CAS: 92761-26-7)

Ecamsule (CAS: 92761-26-7) is a white to off-white crystalline powder with a molecular weight of approximately 382.42 g/mol. It has a low solubility in water but is soluble in organic solvents such as ethanol and acetone. Chemically, it is relatively stable but can degrade under strong acidic or basic conditions. It is often used in sunscreens and has a half-life of several years under normal storage conditions.

Ecamsule (CAS: 92761-26-7) is synthesized via a multi-step process, typically involving the condensation of 2-aminobenzophenone with 4-hydroxydiphenyl ether. The reaction is catalyzed by a Lewis acid and proceeds with high selectivity and yield. Commonly used catalysts include aluminum chloride or boron trifluoride. The overall yield is around 85-90%.

Ecamsule (CAS: 92761-26-7) is primarily used in the cosmetics industry, particularly in sunscreens and personal care products. It is also utilized in the pharmaceutical industry for its photoprotective properties. Additionally, it has emerging applications in the polymer industry for stabilizing UV-sensitive materials and in sensors for detecting UV radiation.

Proper safety measures are essential when handling Ecamsule (CAS: 92761-26-7). It should be handled in a well-ventilated area or a fume hood due to its potential for inhalation hazards. Personal protective equipment (PPE) such as lab coats, gloves, and safety goggles should be worn at all times. Spills should be cleaned up immediately using appropriate absorbents, and the area should be decontaminated. Always refer to the Safety Data Sheet (SDS) for detailed handling and emergency response procedures.
