Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 815.93 g/mol gives (4-Chlorophenyl)trihexadecylsilane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(4-Chlorophenyl)trihexadecylsilane (CAS 18822-35-0), molecular formula C54H103ClSi and molecular weight 815.93 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4-Chlorophenyl)trihexadecylsilane (C54H103ClSi) is characterized by chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
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.
CATO manufactures (4-Chlorophenyl)trihexadecylsilane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
