Chemical Structure
Description
2-(4-Ethylphenyl)-1,3-thiazole-4-carboxylic acid (CAS 847744-15-4) is a high-purity analytical reference standard with the molecular formula C12H11NO2S and a molecular weight of 233.29 g/mol.
The molecular framework of 2-(4-Ethylphenyl)-1,3-thiazole-4-carboxylic acid (C12H11NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
