Chemical Structure
Description
The occurrence of (5-Bromo-1-pentyn-1-yl)trimethylsilane is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(5-Bromo-1-pentyn-1-yl)trimethylsilane (CAS 66927-74-0), molecular formula C8H15BrSi and molecular weight 219.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (5-Bromo-1-pentyn-1-yl)trimethylsilane (C8H15BrSi) is characterized by bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
