(2E,4E)-5-(1H-indol-3-yl)-3-methylpenta-2,4-dienoic acid CAS 1431320-18-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2E,4E)-5-(1H-indol-3-yl)-3-methylpenta-2,4-dienoic acid.

CATO supplies (2E,4E)-5-(1H-indol-3-yl)-3-methylpenta-2,4-dienoic acid (CAS 1431320-18-1), a certified reference material (molecular formula C14H13NO2, MW 227.26 g/mol) for analytical method development and quality control.

Based on its molecular formula C14H13NO2, (2E,4E)-5-(1H-indol-3-yl)-3-methylpenta-2,4-dienoic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 227.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
