Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 202.21 g/mol gives 3-[2-(2-Propynyloxy)phenyl]acrylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-[2-(2-Propynyloxy)phenyl]acrylic acid (CAS 400751-66-8), a certified reference material (molecular formula C12H10O3, MW 202.21 g/mol) for analytical method development and quality control.
3-[2-(2-Propynyloxy)phenyl]acrylic acid (C12H10O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
