Fluticasone Propionate, also known as Flutide, has CAS No. 80474-14-2, molecular formula C25H31F3O5S and molecular weight of 500.57. It is a white chiral corticosteroid solid with a melting point of 275°C and specific optical rotation [α]D +30° (c=0.35). This steroid compound dissolves in DMSO at ≥10 mg/mL, stable under room-temperature storage, with predicted boiling point 568.3±50.0°C and density 1.32±0.1 g/cm³. As a potent anti-inflammatory glucocorticoid raw material widely used in respiratory allergy drug research, we supply high-purity reagent-grade Fluticasone Propionate, deuterated analog Fluticasone Propionate-D5, reference standards and synthetic intermediates. Complete technical documents including InChIKey, MSDS, chiral characterization data, synthetic routes and anti-inflammatory pharmacology data are available, supporting laboratory analytical testing, inhalable steroid formulation development and preclinical pharmaceutical research for asthma and allergic rhinitis treatment.
