Study of the Reaction Derivatization Glyphosate and Aminomethylphosphonic Acid (AMPA) with N,O-Bis(trimethylsilyl)trifluoroacetamide
Abstract: This work aimed to study the derivatization unprecedented of glyphosate and AMPA solutions using N,O-bis (trimethylsilyl)trifluoroacetamide (BSTFA) combined with trimethylchlorosilane (TMCS), evaluating the composition of the reaction medium, use of ultrasound, volume of BSTFA:pyridine and pH of the reaction medium. From this study it was inferred that the reaction medium was composed of BSTFA:pyridine in ratio 60:100, respectively, without ultrasonic vibration and pH adjustment that provide optimal conditions for analysis by GC-MS. Furthermore, the methodology used was simple and fast, and that was the most practical method commonly used.
