Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(Anthracen-9-ylmethylene)-1H-indene-1,3(2H)-dione.
2-(Anthracen-9-ylmethylene)-1H-indene-1,3(2H)-dione (CAS 31060-60-3) is a high-purity analytical reference standard with the molecular formula C24H14O2 and a molecular weight of 334.37 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, 2-(Anthracen-9-ylmethylene)-1H-indene-1,3(2H)-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 334.37 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.
