Standards are required in quantitative NMR (qNMR) to obtain accurate and precise results. In this study acetanilide was established and used as a primary standard. Six other chemicals were selected as secondary standards: 3,4,5-trichloropyridine, dimethylterephthalate, maleic acid, 3-sulfolene, 1,4-bis(trimethylsilyl)benzene, and
