Reports summarize nitrogen compounds research from Dr. Reddy's Laboratories Ltd.

2010 JUL 28 -- Scientists discuss in 'Determination of the quaternary ammonium compound trospium in human plasma by LC-MS/MS: application to a pharmacokinetic study' new findings in nitrogen compounds. According to recent research from Hyderabad, India, "A highly sensitive, specific and evaporation free SPE extraction, LC-MS/MS method has been developed for the estimation of trospium in human plasma using trospium-d8 as an internal standard (IS). The analyte was separated using isocratic mobile phase on reverse phase column and analyzed by MS/MS in the multiple reaction monitoring mode using the respective [M(+)] cations, m/z 392-164 for trospium and m/z 400-172 for the...
