Chemical Structure
Description
(2R)-2-[(1E)-3-(4’-Chloro-2’-methyl[1,1’-biphenyl]-3-yl)-3-hydroxy-1-propen-1-yl]-5-oxo-1-pyrrolidineheptanoic Acid (CAS 493035-81-7) is a high-purity analytical reference standard with the molecular formula C27H32ClNO4 and a molecular weight of 470.00 g/mol.
(2R)-2-[(1E)-3-(4’-Chloro-2’-methyl[1,1’-biphenyl]-3-yl)-3-hydroxy-1-propen-1-yl]-5-oxo-1-pyrrolidineheptanoic Acid (C27H32ClNO4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
