General description
Application
It may be used as a derivatizing reagent for the analysis of bioamines and their acidic metabolites, phenol, hydroquinone and catechol in urine samples, mixtures of free fatty acids and metal soaps in paint samples using gas chromatography/mass spectrometry (GC/MS).
Features and Benefits
- HMDS is inexpensive and has a relatively low boiling point (124-127 °C).
- It can be used without solvent but its silylating power can be increased by various (mostly acidic) catalysts.
- The only reaction byproduct, ammonia, can leave the reaction mixture as the reaction goes to completion.
