Chemical Structure

Benzene, ethenyl-, polymer with 2-methyl-1-propene CAS 9011-12-5 chemical structure

Description

Benzene, ethenyl-, polymer with 2-methyl-1-propene (CAS 9011-12-5) is a high-purity analytical reference standard with the molecular formula C8H8C4H8 and a molecular weight of 160.26 g/mol.

The molecular framework of Benzene, ethenyl-, polymer with 2-methyl-1-propene (C8H8C4H8) is characterized by an aromatic ring system. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), Benzene, ethenyl-, polymer with 2-methyl-1-propene 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.
