    • Although a weak signal with RT around 15.3 min and m/z values corresponding to rapamycin can be detected, it is likely to be a different isomeric compound because a similar signal was observed for secorapamycin solutions

    • No time-dependent change in the isomer ratio (∼9.5) could be detected in the rapamycin solutions with different concentrations of ammonium acetate. However, it takes ca 5 days to reach approximately the same ratio in 30/70 v/v MeCN solution containing 7 mM acetate buffer with apparent pH of 4.95.

    • The trans/cis ratio was estimated from the integrals for the H2 signals assigned to trans- and cis-rotamers. The estimation procedure is associated with significant uncertainty because of the signal overlap.
