Chemical Structure

n-Octacosane-d58 CAS 16416-33-4 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 n-Octacosane-d58 (CAS 16416-33-4), a certified reference material (molecular formula C28D58, MW 453.12 g/mol) for analytical method development and quality control.

Owing to deuterium isotope labeling, a polycyclic aromatic system, n-Octacosane-d58 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 453.12 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), n-Octacosane-d58 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.
