Detailed Description

Testosterone propionate Product Name: testosterone propionate English Name: Testosterone Propionate CAS number: no CAS number information Packing specification: the specification Specifications: 25mg Product Description: testosterone propionate Testosterone propionate Pinyin names: Bingsuan Gaotong English Name: Testosterone Propionate Page number: 2000 edition two 104 C22H32O3 344.49 This product is 17 beta hydroxy androst 4 ene - 3 - keto ester. According to the calculation of dry goods, including C22H32O3 should be 97 % 103%. [ character ] this product is white crystal or white crystalline powder; odorless. This product is easily dissolved in chloroform, in ethanol or ether easily soluble in ethyl acetate, dissolved in vegetable oil, slightly Soluble, insoluble in water. The melting point of the product melting point ( Annex VI C ) ranged from 118 to 123 DEG c.. The specific rotation of the product, precision, plus ethanol dissolved and diluted into quantitative 1ml each containing about 10mg solution, According to the determination of ( Annex VI E ), specific rotation for 84 degrees to 90 degrees. Discrimination [ ] (1 ) the product of about 0.1g, plus ethanol hydrogen potassium hydroxide solution ( 1, 100) 10ml, heated to reflux for 1 Hours, put cold water, 10ml, with ice bath cooling and shaking to crystallize, placed, filtration; crystallization of ice To wash lotion was neutral, and 105 degrees in the dry, according to the determination of ( Annex VI C ), melting point of 150 to 156 DEG C. ( 2) the goods should be infrared light absorption pattern contrast pattern ( spectral set 72) consistent. [ check ] other steroidal apply proper amount of this product, precision, and methanol respectively, each made of 1ml containing 1mg for the test Solution and each 1ml with 0.02mg control solution. According to content determination under the chromatographic conditions were test, reference solution 5 u l injected into the liquid chromatograph, adjusting the detection sensitivity, make the main component of the full range of peak height recorder. And then take For the sample solution and the control solution of the 5 U L, injected into the liquid chromatograph, recording chromatogram to principal component peak retention time 2 times. For the sample solution such as display impurity peak, shall not exceed 4, the impurity peak area and shall not be greater than that of the control solution. The area of the principal peak 1 / 2 and 3 / 4. Dry weightlessness take the goods, at a temperature of 105 DEG C dried to constant weight, weight loss shall not exceed 0.5% ( Appendix L ). [ ] according to content determination by high-performance liquid chromatography ( Appendix V D ) determination. Chromatographic condition and system suitability test with eighteen alkyl silane bonded silica as filler; methanol - water ( 78: 22 ) as mobile phase; the detection wavelength was 254nm. Number of theoretical plates by testosterone propionate peak calculation should not be less than 1000, testosterone propionate Peak and the internal standard substance peak separation shall comply with the requirements. Internal standard solution preparation and nandrolone about 40mg, accurately weighed, the 25mg flask, to dissolved in methanol and Dilute to the mark, shake, that is. Determination of testosterone propionate and control about 25mg, accurately weighed, the 25ml flask, with methanol dissolved and diluted To scale, shake; precision measuring the solution with internal standard solution of the 5ml, the 25ml flask, dilute to the mark with methanol, Shake well, taking 5 u l injected into the liquid chromatograph, recording chromatogram; other take this amount of goods, with determination, by internal standard method with a peak Area calculation, that is. [ category ] androgen drugs. [ storage ] shading, seal preservation. Key words: the use of testosterone propionate testosterone propionate, quotation, the traits of testosterone propionate testosterone propionate, manufacturer, testosterone propionate
