Chemical Structure
Description
The occurrence of methyl 3-hydroxy-2-methyl-2-phenylpropanoate 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.
methyl 3-hydroxy-2-methyl-2-phenylpropanoate (CAS 70397-74-9), molecular formula C11H14O3 and molecular weight 194.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of methyl 3-hydroxy-2-methyl-2-phenylpropanoate (C11H14O3) 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 its high hydrophobicity (logP), 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.
CATO manufactures methyl 3-hydroxy-2-methyl-2-phenylpropanoate 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.
