The occurrence of 5-[(5S,9R)-9-(4-CYanophenyl)-3-(3,5-dichlorophenyl)-1-methyl-2,4-dioxo-1,3,7-triazaspiro[4.4]non-9-yl-methyl]-thiophene-3-carboxylic acid methyl ester is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-[(5S,9R)-9-(4-CYanophenyl)-3-(3,5-dichlorophenyl)-1-methyl-2,4-dioxo-1,3,7-triazaspiro[4.4]non-9-yl-methyl]-thiophene-3-carboxylic acid methyl ester (CAS 882004-95-7) is a high-purity analytical reference standard with the molecular formula C27H22Cl2N4O4S and a molecular weight of 569.46 g/mol.
The molecular framework of 5-[(5S,9R)-9-(4-CYanophenyl)-3-(3,5-dichlorophenyl)-1-methyl-2,4-dioxo-1,3,7-triazaspiro[4.4]non-9-yl-methyl]-thiophene-3-carboxylic acid methyl ester (C27H22Cl2N4O4S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
