Chemical Structure
Description
The occurrence of 3-[(2-hydroxyphenyl)carbamoyl]prop-2-enoic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-[(2-hydroxyphenyl)carbamoyl]prop-2-enoic acid (CAS 83549-07-9) is a high-purity analytical reference standard with the molecular formula C10H9NO4 and a molecular weight of 207.18 g/mol.
The molecular framework of 3-[(2-hydroxyphenyl)carbamoyl]prop-2-enoic acid (C10H9NO4) 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.
