Sun, Xinqi published the artcileDetermination of residual solvents in antazoline hydrochloride, Formula: C17H20ClN3, the publication is Henan Daxue Xuebao, Ziran Kexueban (2009), 39(1), 25-28, database is CAplus.
Capillary gas chromatog. was used to determine residual solventsin antazoline hydrochloride. The linear equation of ethanol is Y = 0.04627 +0.65369X, r = 0.99816 (n = 8), and the range of linearity is 50.35-718.9 g/L and average recovery rate is 98.32% with RSD of 6.79%. The linear equation of toluene is Y = 0.01928 +1.64319X, r = 0.99372 (n = 8), and the range of linearity is 11.6-162.4 g/L and average recovery rate is 98.17% with RSD of 1.5%. The linear equation of DMF is Y = 0.02531 +0.35654X, r = 0.99344 (n = 8), and the range of linearity is 9.8-137.2 g/L and average recovery rate is 98.99% with RSD of 2.34%. Capillary gas chromatog. can be used for determination of antazoline hydrochloride products.
