Ali, Hazim M. published the artcile< Simultaneous Determination of Methyl Nicotinate and Three Salicylic Acid Derivatives in Pain Relief Spray Using HPLC-DAD>, COA of Formula: C7H7NO2, the main research area is methyl nicotinate salicylic acid derivative pain relief spray HPLCDAD.
For the first time, the high-performance liquid chromatog.-diode array detector (HPLC-DAD) approach was operated for the simultaneous assessment of Me nicotinate (MN), Me salicylate (MS), Et salicylate (ES) and 2-hydroxyethyl salicylate (HES) in one pharmaceutical formulation. The limits of detection of MN, HES, MS and ES were found to be 0.0144, 0.0455, 0.0087 and 0.0061μg/mL. The recovery percentages and relative standard deviations ranged from 93.48 to 102.12% and 0.301 to 6.341% for all active ingredients. Accordingly, the previously described data demonstrate the sensitivity, accuracy and precision of the developed method. Therefore, the investigated approach was effectively applied for the simultaneous assessment of MN, HES, MS and ES in DEEP HEAT Spray.
Separations published new progress about Analgesics. 93-60-7 belongs to class pyridine-derivatives, and the molecular formula is C7H7NO2, COA of Formula: C7H7NO2.
