Chemical Structure

Trans-2, Cis-6-Nonadienal CAS 557-48-2 chemical structure

Description

CATO supplies Trans-2, Cis-6-Nonadienal (CAS 557-48-2), a certified reference material (molecular formula C9H14O, MW 138.21 g/mol) for analytical method development and quality control.

The molecular framework of Trans-2, Cis-6-Nonadienal (C9H14O) is characterized by a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
