1189724-35-3 2-Acetyl-3-(4-chlorophenyl)pentanedioic Acid 1,5-Diethyl Ester-d4 Diethyl 2-Aceto-3-(4-chlorophenyl-d4)glutarate (CAS 1189724-35-3), molecular formula C17H21ClO5 and molecular weight 340.80 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1189724-35-3 2-Acetyl-3-(4-chlorophenyl)pentanedioic Acid 1,5-Diethyl Ester-d4 Diethyl 2-Aceto-3-(4-chlorophenyl-d4)glutarate (C17H21ClO5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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).
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.
