Chemical Structure
Description
The occurrence of Methyl 4-(2-methoxyphenyl)-3-oxobutanoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Methyl 4-(2-methoxyphenyl)-3-oxobutanoate (CAS 131644-96-7), a certified reference material (molecular formula C12H14O4, MW 222.24 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, Methyl 4-(2-methoxyphenyl)-3-oxobutanoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 222.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
