Chemical Structure
Description
The occurrence of (5-Chlorothiophen-2-yl)trimethylsilane is closely related to sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (5-Chlorothiophen-2-yl)trimethylsilane (CAS 23395-56-4), a certified reference material (molecular formula C7H11ClSSi, MW 190.77 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, chlorine substitution, (5-Chlorothiophen-2-yl)trimethylsilane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 190.77 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
