Chemical Structure
Description
The occurrence of 4-Methanesulfonyl-2-[(2-methoxyphenyl)formamido]butanoic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Methanesulfonyl-2-[(2-methoxyphenyl)formamido]butanoic acid (CAS 1032039-85-2) is a high-purity analytical reference standard with the molecular formula C13H17NO6S and a molecular weight of 315.34 g/mol.
Structurally, 4-Methanesulfonyl-2-[(2-methoxyphenyl)formamido]butanoic acid (C13H17NO6S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 315.34 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
