Paramethasone is a synthetic fluorinated glucocorticoid of the corticosteroid class, and the material serves as an active pharmaceutical ingredient reference standard rather than as a degradation product. It is used where analysts must identify or quantify the parent drug itself, for example in assay determination, in the standardisation of working solutions and in the verification of chromatographic systems before batch analysis. Additional applications include method development and validation, purity assessment by HPLC, and impurity or residue investigations in which the corticosteroid response must be anchored to a known reference. The compound corresponds to the formula C22H29FO5 with a molecular weight of 392.46 and is an off-white solid. Keep it at -20 °C ± 5 °C and ship with ice packs; pack sizes from 1 mg and 2.5 mg up to 10 mg, 20 mg, 25 mg, 50 mg, 100 mg and 500 mg are available. Further information or a quotation is available on request.
