Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 4-(3,4-dimethoxyphenyl)-4-oxobutanoate.
CATO supplies Ethyl 4-(3,4-dimethoxyphenyl)-4-oxobutanoate (CAS 56872-60-7), a certified reference material (molecular formula C14H18O5, MW 266.29 g/mol) for analytical method development and quality control.
Ethyl 4-(3,4-dimethoxyphenyl)-4-oxobutanoate (C14H18O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Ethyl 4-(3,4-dimethoxyphenyl)-4-oxobutanoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
