1-Methyl-2-(4-methylbenzyl)benzene CAS 21895-17-0 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.

1-Methyl-2-(4-methylbenzyl)benzene (CAS 21895-17-0) is a high-purity analytical reference standard with the molecular formula C15H16 and a molecular weight of 196.29 g/mol.

Structurally, 1-Methyl-2-(4-methylbenzyl)benzene (C15H16) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 196.29 g/mol, it falls into the medium-molecular-weight range. 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).

CATO manufactures 1-Methyl-2-(4-methylbenzyl)benzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
