Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 318974-69-5 Chlorotrimethylsilane - hexamethyldisilazane mixture Hexamethyldisilazane/TMCS 2/1 (v/v) Hexamethyldisilazane/TMCS 2/1 (v/v) in pyridine Silylating mixture Fluka I according to Sweeley.
318974-69-5 Chlorotrimethylsilane - hexamethyldisilazane mixture Hexamethyldisilazane/TMCS 2/1 (v/v) Hexamethyldisilazane/TMCS 2/1 (v/v) in pyridine Silylating mixture Fluka I according to Sweeley (CAS 318974-69-5) is a high-purity analytical reference standard with the molecular formula C6H19NSi2C3H9ClSi and a molecular weight of 270.03 g/mol.
318974-69-5 Chlorotrimethylsilane - hexamethyldisilazane mixture Hexamethyldisilazane/TMCS 2/1 (v/v) Hexamethyldisilazane/TMCS 2/1 (v/v) in pyridine Silylating mixture Fluka I according to Sweeley (C6H19NSi2C3H9ClSi) contains chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
