Chemical Structure

1-Methyl-3-(4-methylbenzyl)benzene CAS 21895-16-9 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 1-Methyl-3-(4-methylbenzyl)benzene.

1-Methyl-3-(4-methylbenzyl)benzene (CAS 21895-16-9), molecular formula C15H16 and molecular weight 196.29 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-Methyl-3-(4-methylbenzyl)benzene (C15H16) is characterized by a polycyclic aromatic 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 1-Methyl-3-(4-methylbenzyl)benzene 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.
