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 (+/-)-(7E,9Z)-(|A-Ionylidene)acetonitrile (2Z,4E)-3-Methyl-5-(2,6,6-trimethyl-1-cyclohexen-1-yl)penta-2,4-dienenitrile 1155402-76-8.
(+/-)-(7E,9Z)-(|A-Ionylidene)acetonitrile (2Z,4E)-3-Methyl-5-(2,6,6-trimethyl-1-cyclohexen-1-yl)penta-2,4-dienenitrile 1155402-76-8 (CAS 1155402-76-8), molecular formula C15H21N and molecular weight 215.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (+/-)-(7E,9Z)-(|A-Ionylidene)acetonitrile (2Z,4E)-3-Methyl-5-(2,6,6-trimethyl-1-cyclohexen-1-yl)penta-2,4-dienenitrile 1155402-76-8 (C15H21N) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
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.
