Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 327.76 g/mol gives 2-chloro-N-{4-[(4-fluorobenzene)sulfonyl]phenyl}acetamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-chloro-N-{4-[(4-fluorobenzene)sulfonyl]phenyl}acetamide (CAS 90309-40-3) is a high-purity analytical reference standard with the molecular formula C14H11ClFNO3S and a molecular weight of 327.76 g/mol.
The molecular framework of 2-chloro-N-{4-[(4-fluorobenzene)sulfonyl]phenyl}acetamide (C14H11ClFNO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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.
