A Spectrophotometric Method for the Determination of α-Tocopherol in Food and Pharmaceutical Samples Using 2-Phenyl-3-(2-Thiazolyl)-5-(2-Thiophene) Tetrazolium Bromide

Mamta Kamboj · Journal of Advances in Biology & Biotechnology · 2026

The novel reagent 2-Phenyl-3-(2-thiazolyl)-5-(2-thiophene)tetrazolium bromide (PTTT) is used in the proposed method to measure α-tocopherol in various edibles. FTIR, NMR, and mass spectral analysis were used to first synthesize and characterize PTTT. The colorless tetrazolium sal...
