- take an appropriate amount of this product and use 0.1 mol/L hydrochloric acid solution was diluted to prepare a solution containing about 30ug of Ambroxol hydrochloride per 1 ml, and the maximum absorption was determined by UV-visible spectrophotometry (General 0401) at a wavelength of 308nm.
examination
- relative density the relative density of this product (General 0601) is 1.10~1.30.
- clarity this product should be clear, if it is turbid, compared with No. 1 turbidity standard solution (General Principles 0902 first method), not more concentrated.
- others shall comply with the relevant provisions under syrup (General rule 0116).
Content determination
- measured by high performance liquid chromatography (General 0512).
- chromatographic conditions and system suitability test with eighteen alkyl silane bonded silica gel as filler (4.0.01mol/L diammonium hydrogen phosphate solution (adjusted to pH 7.0 with phosphoric acid)-acetonitrile (50:50) as mobile phase; The detection wavelength was 248mn. About 5mg of Ambroxol hydrochloride was taken and dissolved with l-lOOMOpl of methanol. Then, formaldehyde solution () was added. The residue is dissolved by adding 5ml of water, diluted to 20ml with mobile phase, and then injected with 20u1 into HPLC. The resolution between Ambroxol peak and impurity I Peak (relative retention time is about 0.8) should be greater than 4.0.
- measuring method: Use internal volume pipette to precisely measure 2ml of the product, put it in a 100ml measuring flask, wash the inner wall of the pipette with mobile phase, wash the liquid into the measuring flask, dilute it to the scale with mobile phase, shake it well, take 5ml accurately, put it in a 20ml measuring flask, dilute to scale with mobile phase, shake well, use it as test solution, take 20 u1 accurately, inject human liquid chromatograph, record chromatogram; in addition, an appropriate amount of Ambroxol hydrochloride reference substance was accurately weighed, dissolved and quantitatively diluted with mobile phase to prepare a solution containing about 30ug per 1 ml, which was operated in the same manner. According to the external standard method to calculate the peak area, that is.
