2-[(2-chlorophenyl)formamido]-4-methanesulfonylbutanoic acid CAS 1025058-89-2

Description

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.

2-[(2-chlorophenyl)formamido]-4-methanesulfonylbutanoic acid (CAS 1025058-89-2), molecular formula C12H14ClNO5S and molecular weight 319.76 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C12H14ClNO5S, 2-[(2-chlorophenyl)formamido]-4-methanesulfonylbutanoic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 319.76 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

As a certified reference material (CRM), 2-[(2-chlorophenyl)formamido]-4-methanesulfonylbutanoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
