Usage and ROS Analysis
mono-tBu-stearate, CAS No. 843666-40-0, is an Semaglutide side chain synthesized from the C18 fatty acid (CAS No. 871-70-5).
There are two routes that would yield Semaglutide side chain CAS No. 1662688-20-1. One is through solid-phase synthesis (lower part) while the other is not (upper part). Both routes converge into this Semaglutide side chain tBuO-Ste-Glu(AEEA-AEEA-OH)-OtBu, CAS No. 1118767-16-0.
The solid phase synthesis building blocks involves three moieties including Fmoc-AEEA (CAS No. 166108-71-0), Fmoc-Glu-OtBu (CAS No. 84793-07-7), and this compound mono-tBu-stearate (CAS No. 843666-40-0).
The other route does not involve solid phase synthesis. It starts from the C18 fatty acid (CAS No. 871-70-5), giving the mono-tBu-stearate. Then mono-tBu-stearate attaches with Glu, and AEEA-dimer.
