Chemical Structure

5-Eicosene(cis/trans mixture) CAS 21400-12-4 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.

CATO supplies 5-Eicosene(cis/trans mixture) (CAS 21400-12-4), a certified reference material (molecular formula C20H40, MW 280.53 g/mol) for analytical method development and quality control.

Owing to an organic framework, 5-Eicosene(cis/trans mixture) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.53 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.

As a certified reference material (CRM), 5-Eicosene(cis/trans mixture) 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.
