Chemical Structure
Description
2-(6,6-Dimethyl-4-oxo-2-phenyl-4,5,6,7-tetrahydro-1H-indol-1-yl)acetic acid (CAS 121626-22-0) is a high-purity analytical reference standard with the molecular formula C18H19NO3 and a molecular weight of 297.35 g/mol.
Based on its molecular formula C18H19NO3, 2-(6,6-Dimethyl-4-oxo-2-phenyl-4,5,6,7-tetrahydro-1H-indol-1-yl)acetic acid contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 297.35 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
