Chemical Structure
Description
Methyl 4-[(4-methylphenyl)(methylsulfonyl)amino]butanoate (CAS 1858242-69-9) is a high-purity analytical reference standard with the molecular formula C13H19NO4S and a molecular weight of 285.36 g/mol.
The molecular framework of Methyl 4-[(4-methylphenyl)(methylsulfonyl)amino]butanoate (C13H19NO4S) 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 the protonation state of its nitrogen-containing groups, 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.
