Chemical Structure

Poly(maleic anhydride-alt-1-octadecene) CAS 25266-02-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Poly(maleic anhydride-alt-1-octadecene).

CATO supplies Poly(maleic anhydride-alt-1-octadecene) (CAS 25266-02-8), a certified reference material (molecular formula C18H36C4H2O3, MW 350.54 g/mol) for analytical method development and quality control.

The molecular framework of Poly(maleic anhydride-alt-1-octadecene) (C18H36C4H2O3) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Poly(maleic anhydride-alt-1-octadecene) 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.
