Zinc undecylenate - Compound zinc fenenate ointment
Authoritative Data Verified Data
This product contains zinc (C22H3804Zn) should be 18.5% ~ 21.5%, containing the total amount of 11 acid should be 19.8% ~ 23.8%.
prescription
zinc (Ⅱ)-(Ⅱ)-(Ⅱ)-(Ⅱ)
Undecanoic acid 50g
Appropriate amount of matrix
lOOOg
trait
This product is white to light yellow ointment.
identification
- take about 5g of this product, add 25ml of ethanol, heat, shake, cool, filter, add several drops of potassium permanganate test solution to the filtrate, and shake, the color of potassium permanganate will disappear.
- take the remaining filter residue, add chloroform 10ml, slightly warm to dissolve, let it cool, add dilute sulfuric acid 20ml, shake, and let it stand once layered, the acid solution of the upper layer shows the identification reaction of the zinc salt (General rule 0301).
- the retention time of the main peak of the test solution should be consistent with the retention time of the main peak of the reference solution in the chromatogram recorded under the determination of the total content of 11 enoic acid.
examination
should be in accordance with the relevant provisions under the item of soft cement (General 0109).
Content determination
- zinc (ii)-(ii)-(ii)-(ii)-(ii)-(ii) zinc-(ii)-(ii)-(ii)-(ii)-(ii)-(ii)-(ii) zinc-(ii)-(I)-(ii)-(ii)-(ii), after the oil layer was clarified, the mixture was heated to 20ml of water, stirred, allowed to stand, cooled, 1 drop of 0.025% methyl red ethanol solution was added, and appropriate amount of ammonia test solution was added until the solution was yellowish, 10ml of ammonia-ammonium chloride buffer solution (pH 10.0) and a small amount of Chrome Black T indicator were added, and the solution was titrated with ethylenediamine tetraacetic acid disodium titration solution (0.05mol/L) until the solution changed from purple to pure blue. Each l of ethylene diamine tetraacetic acid disodium titration solution (0.05mol/L) corresponds to 21.60mg of C22H3804Zn.
- the total amount of 11 enoic acid was measured by gas chromatography (General 0521).
- chromatographic conditions and system suitability test: dimethylpolysiloxane (or similar polarity) was used as the stationary liquid, and the column temperature was 210°C; The inlet temperature and detector temperature were both 250°C. The resolution between internal standard peak and the peak of 11 enoic acid should be greater than 5.0. The theoretical plate number is not less than 10000 based on the calculation of the 11 enoic acid peak.
- preparation of internal standard solution an appropriate amount of 11 alkane was taken and chloroform was added to prepare a solution containing about 3mg per 1 ml.
- determination of this product about 0.4g, precision weighing, set Erlenmeyer flask, add hydrochloric acid solution (l-50)25ml, water bath heating, shaking, until the oil layer is clear, cool, transfer to a separatory funnel and extract three times with chloroform (30ml, 20ml, 20ml). Combine the extracts, put them in a lOOml measuring flask, add 5ml of internal standard solution precisely, dilute them with chloroform to the scale, shake them well, use them as the sample solution, take lul precisely, and inject it into human gas chromatograph, record the chromatogram; Take about 80mg of the reference substance of 11 enoic acid, put it in a 100ml measuring flask, measure it with the same method, and calculate it by peak area according to internal standard method.
category
The same as zinc.
storage
