Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 278.34 g/mol gives 7-Oxo-7-(4-isopropoxyphenyl)heptanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
7-Oxo-7-(4-isopropoxyphenyl)heptanoic acid (CAS 898791-91-8) is a high-purity analytical reference standard with the molecular formula C16H22O4 and a molecular weight of 278.34 g/mol.
The molecular framework of 7-Oxo-7-(4-isopropoxyphenyl)heptanoic acid (C16H22O4) 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.
CATO manufactures 7-Oxo-7-(4-isopropoxyphenyl)heptanoic acid 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.
