Gliclazide EP Impurity F is used as a pharmaceutical reference standard for the identification characterization and analytical testing of gliclazide-related impurities. It is particularly used in analytical method development method validation and pharmaceutical quality-control testing.

Its primary purpose is to help laboratories detect and quantify Gliclazide Impurity F in gliclazide API and pharmaceutical formulations thereby supporting impurity profiling quality assessment and compliance with pharmacopoeial requirements.

Gliclazide EP Impurity F also known as the gliclazide ortho-analog is chemically identified as 2-methyl-N-[(hexahydrocyclopenta[c]pyrrol-2(1H)-yl)carbamoyl]benzene-1-sulfonamide.
