Overview

p-hydroxyacetophenone, quia molecula eius hydroxylum et ketonum circulos in benzene continet, ideo saepe in synthesi organica ut medium agere cum aliis compositis ad summas multas substantias magnas componi solet. Fere ad synthesim intermediarum pharmaceuticae (α-bromo-p-hydroxyacetophenone, medicamenta choleretica, analgesica antipyretica et alia medicamenta), alia (armata, nutrimenta, etc.; pesticides, colores, liquidae materiae crystallinae, etc.).

Applicationem

p-hydroxyacetophenone alba est acus cristalli similis in cella temperie, in caule et foliis scoparia Artemisiae naturaliter occurrens, in radicibus plantarum ut ginseng parve vitis. Adhiberi potest in medicamentis cholereticis fabricandis et aliis materiis rudibus ad synthesim organicam.
