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.
Benzyldimethyldodecylammonium Chloride (CAS 139-07-1) is a high-purity analytical reference standard with the molecular formula C21H38NCl and a molecular weight of 339.99 g/mol.
Owing to a nitrile group, chlorine substitution, Benzyldimethyldodecylammonium Chloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 339.99 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Benzyldimethyldodecylammonium 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.
