Chemical Structure
Description
N-((2-Oxo-1,2-dihydrobenzo[cd]indol-6-yl)methyl)thiophene-2-carboxamide (CAS 526189-13-9) is a high-purity analytical reference standard with the molecular formula C17H12N2O2S and a molecular weight of 308.35 g/mol.
Structurally, N-((2-Oxo-1,2-dihydrobenzo[cd]indol-6-yl)methyl)thiophene-2-carboxamide (C17H12N2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 308.35 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
