This product is a-(l-aminoethyl)-2, 5-dimethoxybenzyl alcohol hydrochloride. The content of C11H17N03 • HC1 shall not be less than 99.0% calculated on a dry basis.
take this product, precision weighing, add water to dissolve and quantitatively dilute to make a solution containing about 30ug per lml, according to UV-visible spectrophotometry (General 0401), the absorbance was measured at a wavelength of 290nm, and the absorption coefficient was 133 to 141.
take 0.20g of this product, Add 10ml of water to dissolve, and measure according to law (General rule 0631). The pH value should be 4.5~6.0.
take this product, add water to dissolve and dilute to make a solution containing about 0401 mg per lml, according to UV-visible spectrophotometry (general rule), at the wavelength of NM, the absorbance should not exceed 0.06.
take this product, add mobile phase to dissolve and dilute to make a solution containing about 1 mg per 1ml as a test solution; Take 1ml for precision measurement and put it in a 100ml measuring flask, dilute to the scale with the mobile phase, shake, and serve as a control solution. According to the high performance liquid chromatography (General 0512) determination, with eighteen alkyl silane bonded silica gel as filler; 0.005mol/L sodium heptane sulfonate solution (with 0.1 mol/L hydrochloric acid solution to adjust the pH value to 3.5)-methanol (58:42) as mobile phase; The detection wavelength was 226mn. The number of theoretical plates shall not be less than 3000 calculated by methoxyl peak, and the degree of separation between methoxyl peak and adjacent impurity peak shall meet the requirements. 20 u1 of the test solution and the control solution were respectively injected into the liquid chromatograph, and the chromatogram was recorded to 2 times of the retention time of the main component peak. If there are impurity peaks in the chromatogram of the test solution, the sum of each impurity peak area shall not be greater than the main peak area of the control solution (1.0%).
take this product, dry at 105°C for 2 hours, loss of weight shall not exceed 0.5% (General rule 0831).
not more than 0.2% (General rule 0841).
take this product about 0.2g, precision weighing, add water 50ml to dissolve, add nitric acid 1ml, according to the potential titration method (General rule 0701), with silver nitrate titration solution (0.lmol/L) titration, silver nitrate titration solution per lml (0.1 mol/L) corresponds to 24.77mg of C11H17N03.
