Procymidone (Standard) is the standard substance of Procymidone, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Procymidone is a broad-spectrum fungicide that inhibits fungal glycerol triester synthesis, thereby disrupting hyphal growth. It is primarily used for grey mould and sclerotium rot and can also act as a competitive androgen receptor (AR) antagonist, interfering with sexual differentiation in male rats.
