Chemical Structure
Description
CATO supplies Methyl 4-(4-methoxyphenyl)butanoate (CAS 20637-08-5), a certified reference material (molecular formula C12H16O3, MW 208.25 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 4-(4-methoxyphenyl)butanoate (C12H16O3) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Methyl 4-(4-methoxyphenyl)butanoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
