Chemical Structure

3,5-Diethyl-1-phenyl-2-propylpyridin-1-ium iodide CAS 6277-85-6 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.

3,5-Diethyl-1-phenyl-2-propylpyridin-1-ium iodide (CAS 6277-85-6), molecular formula C18H24NI and molecular weight 381.30 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3,5-Diethyl-1-phenyl-2-propylpyridin-1-ium iodide (C18H24NI) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 381.30 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), 3,5-Diethyl-1-phenyl-2-propylpyridin-1-ium iodide 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.
