(4Z)-2-[(2,4-Dichlorophenyl)methoxy]-4-(phenylmethylidene)-1,2,3,4-tetrahydroisoquinoline-1,3-dione (CAS 338396-49-9), molecular formula C23H15Cl2NO3 and molecular weight 424.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4Z)-2-[(2,4-Dichlorophenyl)methoxy]-4-(phenylmethylidene)-1,2,3,4-tetrahydroisoquinoline-1,3-dione (C23H15Cl2NO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
