Chemical Structure
Description
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 supplies 66604-31-7 Chloro(dodecyl)dimethylsilane Chloro-dimethyl-dodecylsilane Dimethyldodecylchlorosilane Dodecyldimethylchlorosilane (CAS 66604-31-7), a certified reference material (molecular formula C14H31ClSi, MW 262.93 g/mol) for analytical method development and quality control.
The molecular framework of 66604-31-7 Chloro(dodecyl)dimethylsilane Chloro-dimethyl-dodecylsilane Dimethyldodecylchlorosilane Dodecyldimethylchlorosilane (C14H31ClSi) 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.
As a certified reference material (CRM), 66604-31-7 Chloro(dodecyl)dimethylsilane Chloro-dimethyl-dodecylsilane Dimethyldodecylchlorosilane Dodecyldimethylchlorosilane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
