Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 196.20 g/mol gives 3-(4-Hydroxy-3-methoxyphenyl)propionic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-(4-Hydroxy-3-methoxyphenyl)propionic Acid (CAS 1135-23-5), a certified reference material (molecular formula C10H12O4, MW 196.20 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 3-(4-Hydroxy-3-methoxyphenyl)propionic Acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 196.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
