This product is 17a-methyl-17b-hydroxyandrostin-4-en-3-one. The C20H30O2 content shall be between 97.0% and 103.0% calculated on the dried product.
The melting point of this product (General 0612) is 163~167°C.
take this product, precision weighing, plus ethanol dissolution and quantitative dilution of about 10 mg per lml solution, according to the law (General 0621), the specific rotation was 79 ° to 85 °.
take this product, add methanol to dissolve and dilute to make a solution containing about 0.6mg per 1 ml as a test solution; Take 2ml for precision measurement and put it in a 100ml measuring flask, as a control solution, it was diluted to the scale with methanol and shaken. According to the chromatographic conditions under the content determination item, 10ul of each of the test solution and the control solution are accurately measured and injected into the liquid chromatograph respectively, and the chromatogram is recorded to 2 times of the retention time of the main component peak. If there are no more than 3 impurity peaks in the chromatogram of the test solution, the area of a single impurity peak shall not be more than 0.5 times (1.0%) of the area of the main peak of the control solution, the sum of each impurity peak area shall not be greater than 0.75 times (1.5%) of the main peak area of the control solution. The peaks in the chromatogram of the test solution which were 0.025 times smaller than the main peak area of the control solution were ignored.
take this product, dry at 105°C for 2 hours, loss of weight shall not exceed 1.0% (General rule 0831).
measured by high performance liquid chromatography (General 0512).
using eighteen alkyl silane bonded silica gel as filler; Methanol-water (72:28) as mobile phase; The detection wavelength was 241rmu, methanol was added to dissolve and quantitatively diluted to prepare about 0.lmg solution, take 10ul injection liquid chromatograph, record chromatogram, theoretical plate number calculated by methyltestosterone peak is not less than 1500, methyltestosterone peak and testosterone peak separation should meet the requirements.
take about 10mg of this product, weigh it accurately, put it in a lOOml measuring flask, add methanol to dissolve and dilute it to the scale, shake it well, and use it as a test solution, take 10u1 injection liquid chromatograph, record chromatogram; Take methyltestosterone control, same method determination. According to the external standard method to calculate the peak area, that is.
androgens.
light shielding, sealed storage.
This product contains E. Coli (C20H3002) should be 90.0% ~ 110.0% of the label amount.
This product is white tablet.
take an appropriate amount of fine powder of this product (about 10 mg of methyltestosterone), add ethanol or chloroform 10mU and stir to dissolve methyltestosterone, filter, and evaporate the filtrate on a water bath, the residue was identified according to the test of item (1) and item (3) under the item of methyltestosterone, and showed the same result.
Take 20 tablets of this product, precise weighing, fine grinding, precise weighing appropriate amount (about 10mg equivalent to methyltestosterone), put it in a 100ml measuring flask, add the appropriate amount of methanol, ultrasound to dissolve methyltestosterone, cool, dilute to the scale with methanol, shake well, filter, take the filtrate and measure it according to the method under the item of methyltestosterone content determination.
Same as methyltestosterone.
