Description
N,O-Bis(trimethylsilyl)trifluoroacetamide is a minimum 98 % GC-grade silylation reagent widely applied in gas chromatographic sample preparation. It carries CAS number 25561-30-2, empirical formula C₈H₁₈F₃NOSi₂ and a molar mass of 257,41 g/mol, with a density of 0,97 g/cm³. Boiling point is reported at 146 °C and flash point at 36 °C, supporting risk assessment during heated derivatisation steps. The 10 g glass pack from manufacturer Carl ROTH provides a practical quantity for method development and routine GC workflows that require formation of volatile trimethylsilyl derivatives, including trifluoroacetyl-related chemistry. Laboratories in organic analysis, metabolite profiling and environmental testing rely on such reagents to improve peak shape and detectability of polar analytes. Clear assay and physicochemical data allow straightforward integration into validated SOPs. This BSTFA-type material is intended for professional GC derivatisation rather than general synthesis use.

Questions about N,O-Bis(trimethylsilyl)-trifluoroacet-, amide, min. 98 %, for GC, 10 g, glass
What is this article?
N,O-Bis(trimethylsilyl)-trifluoroacet-, amide, min. 98 %, for GC, 10 g, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Inorganic salts, inside Inorganic chemicals, in Lab chemicals.
An inorganic salt is an ionic solid, a chloride, a sulfate, a nitrate, a phosphate. The degree of hydration changes the mass that contains one mole of the ion. Analytical grade limits the foreign ions. A hydrate and the anhydrous salt are not interchangeable by weight.
An inorganic chemical is a salt, an acid or base in solid form, a metal, an oxide, or an element. The waters of hydration are part of the formula: a hydrate and an anhydrous salt are different masses for the same ion. Trace metals matter when the salt will be used in analysis. Nanomaterials add particle size to the specification. Look the substance up on PubChem. Hazard classes are on ECHA, under the CLP Regulation and REACH. Transport of the dangerous ones is explained by the UNECE.
