Chemical Structure
Description
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.
77727-18-5 4H-1-Benzopyran-4-one, 2,3-dihydro-5,7-dimethoxy-8-(3-methyl-2-butenyl)-2-phenyl-, (2S)- (CAS 77727-18-5) is a high-purity analytical reference standard with the molecular formula C22H36O4 and a molecular weight of 364.52 g/mol.
The molecular framework of 77727-18-5 4H-1-Benzopyran-4-one, 2,3-dihydro-5,7-dimethoxy-8-(3-methyl-2-butenyl)-2-phenyl-, (2S)- (C22H36O4) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
