(E)-1-Octadecyl-4-styrylpyridin-1-ium bromide CAS 126115-86-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-1-Octadecyl-4-styrylpyridin-1-ium bromide.

(E)-1-Octadecyl-4-styrylpyridin-1-ium bromide (CAS 126115-86-4), molecular formula C31H48NBr and molecular weight 514.64 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (E)-1-Octadecyl-4-styrylpyridin-1-ium bromide (C31H48NBr) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 514.64 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.

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), (E)-1-Octadecyl-4-styrylpyridin-1-ium bromide 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.
