*Regisil® BSTFA + 1% TMCS (RC-2), CAS # 25561-30-2; 75-77-4, 25 gm

BSTFA reacts faster and more completely than BSA, due to the trifluoroacetaminde leaving group. The high volatility of BSTFA and its byproducts results in non-co-elution of early eluting peaks. Additionally, the highly volatile and stable products result in low detector noise and fouling. The addition of TMCS to BSTFA catalyzes reactions of hindered functional groups and other difficult functional groups, such as secondary hydroxyls and amines.
