Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2Z)-7-(4-Chlorophenoxy)-2-[(3-methylthiophen-2-yl)methylidene]-3-phenyl-2,3-dihydro-1H-inden-1-one.
(2Z)-7-(4-Chlorophenoxy)-2-[(3-methylthiophen-2-yl)methylidene]-3-phenyl-2,3-dihydro-1H-inden-1-one (CAS 337921-32-1), molecular formula C27H19ClO2S and molecular weight 442.96 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, (2Z)-7-(4-Chlorophenoxy)-2-[(3-methylthiophen-2-yl)methylidene]-3-phenyl-2,3-dihydro-1H-inden-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 442.96 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
