Chemical Structure
Description
2-(4-(Tert-butyl)phenyl)-8-methylquinoline-4-carboxylic acid (CAS 897566-25-5) is a high-purity analytical reference standard with the molecular formula C21H21NO2 and a molecular weight of 319.40 g/mol.
The molecular framework of 2-(4-(Tert-butyl)phenyl)-8-methylquinoline-4-carboxylic acid (C21H21NO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
