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.
Piperazine-1,4-diylbis((5-chloro-2-isobutoxyphenyl)methanone) (CAS 882864-19-9), molecular formula C26H32Cl2N2O4 and molecular weight 507.45 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Piperazine-1,4-diylbis((5-chloro-2-isobutoxyphenyl)methanone) (C26H32Cl2N2O4) 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 the protonation state of its nitrogen-containing 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.
