Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 262.33 g/mol gives 4-[(1-Phenyl-1H-imidazol-2-yl)sulfanyl]butanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-[(1-Phenyl-1H-imidazol-2-yl)sulfanyl]butanoic acid (CAS 478046-25-2), a certified reference material (molecular formula C13H14N2O2S, MW 262.33 g/mol) for analytical method development and quality control.
The molecular framework of 4-[(1-Phenyl-1H-imidazol-2-yl)sulfanyl]butanoic acid (C13H14N2O2S) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
