Acylation Derivatization Reagents
• Most commonly used for electron capture detection.
• React with alcohols, amines, and phenols.
• Frequently used for drugs of abuse confirmation.
Acylation reagents offer the same advantage available from si-
lylation reagents: creating less polar, more volatile derivatives.
In comparison to silylating reagents, the acylating reagents can
more readily target highly polar multifunctional compounds,
such as carbohydrates and amino acids. In addition, acylating
reagents offer the distinct advantage of introducing electron-
capturing groups, thus enhancing detectability during analysis.

Dimethyldichlorosilane (DMDCS) (75-78-5)
Dimethyldichlorosilane (DMDCS) Deactivating Agent
• Easy deactivation of liners and other glass surfaces.
• Convenient—25 mL bottle deactivates 60 inlet liners.
• Tested to ensure consistent quality and effectiveness.
Restek offers dimethyldichlorosilane (DMDCS) for deactivating
liners and other glassware. DMDCS reacts with active hydroxyl
groups on the glass surface to produce a deactivated surface. A
simple, step-by-step procedure is included with the product.
