1-Chloro-5-triethylsilyl-1-pentyne CAS 892156-07-9

Description

The occurrence of 1-Chloro-5-triethylsilyl-1-pentyne is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-Chloro-5-triethylsilyl-1-pentyne (CAS 892156-07-9), a certified reference material (molecular formula C11H21ClSi, MW 216.82 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H21ClSi, 1-Chloro-5-triethylsilyl-1-pentyne contains chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 216.82 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
