3,4,9,10-Tetramethylperylene CAS 120651-41-4

Description

The occurrence of 3,4,9,10-Tetramethylperylene is closely related to a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3,4,9,10-Tetramethylperylene (CAS 120651-41-4), a certified reference material (molecular formula C24H20, MW 308.42 g/mol) for analytical method development and quality control.

Structurally, 3,4,9,10-Tetramethylperylene (C24H20) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 308.42 g/mol, it falls into the moderately-high-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
