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.
N,N-Dibutyl-N-(3-(trimethoxysilyl)propyl)butan-1-aminium chloride (CAS 143203-33-2), molecular formula C18H42NO3SiCl and molecular weight 384.07 g/mol, is a CATO reference standard with documented purity and traceability.
N,N-Dibutyl-N-(3-(trimethoxysilyl)propyl)butan-1-aminium chloride (C18H42NO3SiCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), N,N-Dibutyl-N-(3-(trimethoxysilyl)propyl)butan-1-aminium chloride 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.
