客户希望了解以下情况：1，此产品的合成，你是否有参考文献？若有，文献中

Customers want to know the following: <br>1. Do you have references for the synthesis of this product? If so, are there any analytical data in the literature? Especially for HNMR, if there are data in the literature, is it consistent with your test results? <br><br>2. Do intermediates 5 and 6 have HNMR and HPLC spectra? Are these two intermediates single diastereomers detected by HPLC and HNMR? <br><br>3. You want to buy a standard sample, but did not buy it. Does the supplier of the standard sample have the previous NMR spectrum of this product? Can you get this map from them for comparison

Customers want to know:<br>1, the synthesis of this product, do you have a reference? If so, is there analytical data in the literature? HNMR in particular, if there is data in the literature, is it consistent with your test results?<br><br>2, intermediates 5 and 6 have HNMR and HPLC maps, these two intermediates with HPLC and HNMR detection is a single non-contrast isomers?<br><br>3, you want to buy samples, but not, the standard supplier has previously this product NMR map? Can you get to this map from their place for comparison.
