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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
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.

Solubility
Soluble in water (reacts).

Notes
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.
