Items	Standard
Identification A	The infrared absorption spectrum of the sample is concordant with that of the standard.
Identification B	The principal spot obtained from the Test solution corresponds in appearance and RF value to that obtained from Standard solution A.
Identification B	The test is not valid unless the chromatogram obtained with Standard solution B shows four clearly discernible spots, disregarding any spots at the origin.
Residue on ignition	Not more than 0.1%
Heavy metals	Not more than 5µg per g.
Clarity and color of solution	The solution(1g in 10ml of boiling water) isclear and nearly colorless.Determine the absorbance of this solution at a wavelength of 400 nm.The absorbance divided by the path length,in cm,is not more than 0.04.
Optical rotation	+54.4°~+55.9°, calculate on the anhydrous basis,determined at 20°
Acidity or alkalinity	Add 0.3ml of phenolphthalein TS: the solution is colorless, and not more than 0.4 ml of 0.1 N sodium hydroxide is required to produce a pink to red color.
