1,1,3,3-Tetramethyl-1,3-dihydro-2H-inden-2-one CAS 5689-12-3

Description

Compared with other compounds in its class, the molecular weight of 188.27 g/mol gives 1,1,3,3-Tetramethyl-1,3-dihydro-2H-inden-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,1,3,3-Tetramethyl-1,3-dihydro-2H-inden-2-one (CAS 5689-12-3), molecular formula C13H16O and molecular weight 188.27 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,1,3,3-Tetramethyl-1,3-dihydro-2H-inden-2-one (C13H16O) is characterized by a hydroxyl group, an ether linkage, 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 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.
