Description
The occurrence of 2-({4-[(1,3-dioxo-2,3-dihydro-1H-inden-2-ylidene)methyl]-2,5-dimethylpiperazin-1-yl}methylidene)-2,3-dihydro-1H-indene-1,3-dione is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-({4-[(1,3-dioxo-2,3-dihydro-1H-inden-2-ylidene)methyl]-2,5-dimethylpiperazin-1-yl}methylidene)-2,3-dihydro-1H-indene-1,3-dione (CAS 42986-03-8), a certified reference material (molecular formula C26H22N2O4, MW 426.46 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2-({4-[(1,3-dioxo-2,3-dihydro-1H-inden-2-ylidene)methyl]-2,5-dimethylpiperazin-1-yl}methylidene)-2,3-dihydro-1H-indene-1,3-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 426.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
