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 (E)-2-(4-(tert-Butoxycarbonyl)piperazin-1-yl)-4-phenylbut-3-enoicacid.
(E)-2-(4-(tert-Butoxycarbonyl)piperazin-1-yl)-4-phenylbut-3-enoicacid (CAS 853681-16-0), molecular formula C19H26N2O4 and molecular weight 346.42 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (E)-2-(4-(tert-Butoxycarbonyl)piperazin-1-yl)-4-phenylbut-3-enoicacid (C19H26N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 346.42 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
