7(Z)-Pentacosene CAS 63623-49-4 chemical structure

Description

CATO supplies 7(Z)-Pentacosene (CAS 63623-49-4), a certified reference material (molecular formula C25H50, MW 350.66 g/mol) for analytical method development and quality control.

Owing to an organic framework, 7(Z)-Pentacosene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 350.66 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
