Chemical Structure
Description
CATO supplies (2E)-3-(2H-1,3-benzodioxol-5-yl)prop-2-enoyl chloride 26930-49-4 KS-00001L6C (CAS 26930-49-4), a certified reference material (molecular formula C10H7ClO3, MW 210.61 g/mol) for analytical method development and quality control.
The molecular framework of (2E)-3-(2H-1,3-benzodioxol-5-yl)prop-2-enoyl chloride 26930-49-4 KS-00001L6C (C10H7ClO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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 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.
