N-nitroso desmethyl Tetracycline Standard

[Ymatar]

Hi All,

Could anyone kindly assist by suggesting potential suppliers for the N-nitroso desmethyl tetracycline impurity? We’ve made several attempts to source it through various channels, but unfortunately without success.

It appears that this impurity is particularly difficult to synthesize or obtain. If anyone has any leads, experience, or suggestions, your input would be greatly appreciated.
