Chemical Structure

(2,5-Dimethylpiperazine-1,4-diyl)bis(ethane-2,1-diyl) bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) CAS 76891-00-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2,5-Dimethylpiperazine-1,4-diyl)bis(ethane-2,1-diyl) bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate).

(2,5-Dimethylpiperazine-1,4-diyl)bis(ethane-2,1-diyl) bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (CAS 76891-00-4), molecular formula C44H70N2O6 and molecular weight 723.04 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (2,5-Dimethylpiperazine-1,4-diyl)bis(ethane-2,1-diyl) bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (C44H70N2O6) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

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.
