Category	Description (English Translation)
Uses & Synthesis Methods 3-Phenyl-1,4,2-dioxazol-5-one	Uses: This compound serves as an organic synthesis intermediate. It can be used in the fields of pharmaceuticals, pesticides, polymer modification, and notably as an electrolyte additive for lithium batteries to enhance high-temperature storage and cycling performance [citation:2]. Synthesis Methods: A "one-pot" method is available. Under an inert atmosphere and basic conditions, a benzoic acid derivative (e.g., benzoic acid, benzoyl chloride, methyl benzoate) reacts with hydroxylamine hydrochloride to form a benzohydroxamic acid intermediate in situ. Subsequently, without isolation, this system reacts with triphosgene to yield the target product. This method features mild conditions, simple operation, and inexpensive raw materials, making it suitable for industrial production [citation:2].
