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 (S)-N-[(1E)-2-cyclohexylprop-2-en-1-ylidene]-2-methylpropane-2-sulfinamide.
(S)-N-[(1E)-2-cyclohexylprop-2-en-1-ylidene]-2-methylpropane-2-sulfinamide (CAS 1269141-25-4), molecular formula C13H24NOS and molecular weight 242.40 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-N-[(1E)-2-cyclohexylprop-2-en-1-ylidene]-2-methylpropane-2-sulfinamide (C13H24NOS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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. 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.
