Chemical Structure
Description
2-((4-Chlorobutyl)dimethylsilyl)pyridine (CAS 243468-43-1) is a high-purity analytical reference standard with the molecular formula C11H18ClNSi and a molecular weight of 227.81 g/mol.
Owing to a nitrile group, chlorine substitution, 2-((4-Chlorobutyl)dimethylsilyl)pyridine is typically white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 227.81 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
As a certified reference material (CRM), 2-((4-Chlorobutyl)dimethylsilyl)pyridine 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.
