2-{[4-(propan-2-yl)phenyl]methylidene}-2,3-dihydro-1H-indene-1,3-dione (CAS 24760-30-3) is a high-purity analytical reference standard with the molecular formula C19H16O2 and a molecular weight of 276.33 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, 2-{[4-(propan-2-yl)phenyl]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 276.33 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).
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.
CATO manufactures 2-{[4-(propan-2-yl)phenyl]methylidene}-2,3-dihydro-1H-indene-1,3-dione under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
