Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 2-methyl-2-(3,4,5-trimethoxyphenyl)propanoate.
Methyl 2-methyl-2-(3,4,5-trimethoxyphenyl)propanoate (CAS 78131-14-3), molecular formula C14H20O5 and molecular weight 268.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 2-methyl-2-(3,4,5-trimethoxyphenyl)propanoate (C14H20O5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
