Detailed Description

Nandrolone Product Name: nandrolone English Name: Nandrolone Phenylpropionate CAS number: 62-90-8 Packaging specifications: 1kg Specifications : 97% ~ 103% Product Description: nandrolone Pinyin Name: Benbingsuan Nuolong English Name: Nandrolone Phenylpropionate Page number: 2000 edition two 365 C27H34O3 406.57 The product of 17 hydroxy estradiol - 4 - Xi - 3 - ketone - 3 - styrene acrylic ester. According to the calculation of dry goods, including C27H34O3 From 97% to 103%. [ character ] this product is white or white crystalline powder; have a special smell. The goods in the ethanol dissolved, slightly soluble in vegetable oil, almost insoluble in water. The melting point of the product melting point ( Annex VI C ) ranged from 93 to 99 DEG c.. The specific rotation of the product, precision that will add two oxygen, six ring dissolved and diluted into quantitative 1ml each containing about 10mg The solution, according to the determination of ( Annex VI E ), specific rotation for 48 degrees to 51 degrees. Discrimination [ ] (1 ) the product of about 50mg, plus 2ml methanol dissolved, and semicarbazide hydrochloride solution 4ml, heating and back Flow 30 minutes, on the water bath concentration, put cold precipitation, filtration; methanol washing several times, and then water wash, in 105 DEG C dried ( Annex VI, according to the determination of C ), the melting point of about 182 DEG C, melting and decomposition. ( 2) the goods should be infrared light absorption pattern contrast pattern ( spectral set 231) consistent. [ check ] other steroidal apply proper amount of this product, precision, using methanol as solvent, 1ml prepared into each containing 2 The Mg solution ( 1 ) and each 1ml 0.04mg containing solution ( 2). With determination under the methods and solution, 8 l injection Into the liquid chromatograph, adjusting the detection sensitivity, make the main component of the full range of peak height recorder. Then solution ( 1) and ( 2) the 8 U L, are injected into the liquid chromatograph. Recording chromatogram to principal component peak retention time 1.5 times. Soluble Liquid ( 1) shows the impurity peak number can not exceed 3, the impurity peak area and total solution ( 2) are not larger than the peak Area 1 / 2 and 3 / 4. Loss on drying the product containing phosphorus pentoxide, drying, vacuum drying to constant weight loss, weight not over 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 ( 82: 18 ) as mobile phase; the detection wavelength was 241nm. Number of theoretical plates according to nandrolone peak calculation should not be less than 2300, propionic acid Internal standard substance nandrolone peak and peak separation shall comply with the requirements. Internal standard solution preparation and testosterone propionate is about 50mg, accurately weighed, the 50ml flask, adding methanol dissolved and diluted Release to scale, shake, that is. Determination for nandrolone control about 50mg, accurately weighed, the 25ml flask, adding methanol dissolved and diluted Release to scale, shake; precision measuring the solution with internal standard solution of the 5ml, the 25ml flask, with methanol diluted to moment Degree, shake; take 8 u l injected into the liquid chromatograph, recording chromatogram; other take this amount of goods, with determination, by internal standard method Calculated by peak area, namely. [ category ] anabolic agents. [ storage ] shading, seal preservation. [ ] nandrolone injection preparation Key words: nandrolone quotation, nandrolone manufacturer, nandrolone use, Nandrolone traits, nandrolone
