Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[(4-Fluorophenyl)sulfanyl]-1-(4-methoxyphenyl)-2-phenyl-6,7-dihydro-1H-indole-5-carbaldehyde.
4-[(4-Fluorophenyl)sulfanyl]-1-(4-methoxyphenyl)-2-phenyl-6,7-dihydro-1H-indole-5-carbaldehyde (CAS 477869-30-0) is a high-purity analytical reference standard with the molecular formula C28H22FNO2S and a molecular weight of 455.54 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 4-[(4-Fluorophenyl)sulfanyl]-1-(4-methoxyphenyl)-2-phenyl-6,7-dihydro-1H-indole-5-carbaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 455.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
