Benzoin Ethyl Ether, identified by CAS number 574-09-4, is a fascinating organic compound with significant industrial relevance. As a derivative of benzoin, it possesses a unique molecular structure that lends itself to specialized applications, most notably as a photosensitizer and a component in light-curing systems. Understanding its chemical properties is fundamental for R&D scientists and product formulators seeking to leverage its capabilities.

Chemically, Benzoin Ethyl Ether has the molecular formula C16H16O2 and a molecular weight of approximately 240.30. It typically presents as a light yellow powder or crystalline solid. A key characteristic is its solubility profile: it dissolves readily in common organic solvents such as acetone, chloroform, ethanol, ether, and benzene, but remains insoluble in water. This solubility makes it amenable to incorporation into various solvent-based formulations used in industrial processes.

The primary industrial application of Benzoin Ethyl Ether is its role as a photosensitizer, particularly within the printing industry. Here, it is used to manufacture photosensitive resin plates. When exposed to UV light, the compound initiates a chemical reaction that hardens specific areas of the plate, creating the relief or image necessary for printing. This light-curing capability extends to other industrial applications where controlled polymerization or cross-linking is required.

For manufacturers and distributors, ensuring a reliable supply of high-purity Benzoin Ethyl Ether (often specified at ≥97.0% purity by Gas Chromatography) is crucial. The physical form, whether white or yellow crystals, and adherence to quality standards are key metrics for buyers. Companies looking to buy this compound can often find it from chemical manufacturers and suppliers who specialize in organic intermediates, with competitive pricing available for bulk purchases.

In conclusion, Benzoin Ethyl Ether (CAS 574-09-4) is a valuable chemical intermediate owing to its excellent photosensitizing properties. Its application in light-curing technologies, especially in the printing sector, highlights its importance in modern manufacturing. Sourcing from reputable manufacturers ensures the quality and consistency required for demanding industrial processes.
