7-(4-(tert-Butyl)phenyl)-2-methyl-1H-indene CAS 245653-52-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-(4-(tert-Butyl)phenyl)-2-methyl-1H-indene.

7-(4-(tert-Butyl)phenyl)-2-methyl-1H-indene (CAS 245653-52-5) is a high-purity analytical reference standard with the molecular formula C20H22 and a molecular weight of 262.39 g/mol.

Structurally, 7-(4-(tert-Butyl)phenyl)-2-methyl-1H-indene (C20H22) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 262.39 g/mol, it falls into the medium-molecular-weight range. 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), 7-(4-(tert-Butyl)phenyl)-2-methyl-1H-indene 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.
