Chemical Structure
Description
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.
1-(4-Acetylphenyl)-2,6,6-trimethyl-1,5,6,7-tetrahydro-4H-indol-4-one (CAS 627835-15-8) is a high-purity analytical reference standard with the molecular formula C19H21NO2 and a molecular weight of 295.38 g/mol.
The molecular framework of 1-(4-Acetylphenyl)-2,6,6-trimethyl-1,5,6,7-tetrahydro-4H-indol-4-one (C19H21NO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
