Aplicaciones

It finds its application in the preparation of N-tert-butyldimethylsilyl ethanolamines resulting from hydrolysis of nitrogen mustards and a silylating agent used in the derivatization of various organic compounds (such as amino acids) for gas chromatography-mass spectrometry (GC-MS) analysis and selective O-silylation of N,O-diacylhydroxylamines and GLC derivatization.

Notas

Moisture sensitive. Store away from water/moisture and oxidizing agents. Keep the container tightly closed and place it in a cool, dry and well ventilated condition. Store away from electrostatic charges. Keep ignition sources away.
