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 (E)-3-(benzo[d][1,3]dioxol-5-yl)-2-cyanoacrylic acid.
CATO supplies (E)-3-(benzo[d][1,3]dioxol-5-yl)-2-cyanoacrylic acid (CAS 49711-55-9), a certified reference material (molecular formula C11H7NO4, MW 217.18 g/mol) for analytical method development and quality control.
The molecular framework of (E)-3-(benzo[d][1,3]dioxol-5-yl)-2-cyanoacrylic acid (C11H7NO4) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
