Derivatization reagents for GC, silylation, Silyl-991

This mixture of silylating agent SILYL-991 consists of BSTFA – TMCS (99:1) ready for convenient application. BSTFA alone generally reacts with all organic material present, but may not react with some amides, secondary amines and hindered hydroxyl groups. SILYL-991 on the other hand is also suitable for these compounds. These products contain hazardous substances that must be labelled.
