Description

CATO supplies 1858249-90-7 4-[(5-Chloro-2-methylphenyl)(methylsulfonyl)amino]butanoic acid MFCD28954544 (CAS 1858249-90-7), a certified reference material (molecular formula C12H16ClNO4S, MW 305.78 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 1858249-90-7 4-[(5-Chloro-2-methylphenyl)(methylsulfonyl)amino]butanoic acid MFCD28954544 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), 1858249-90-7 4-[(5-Chloro-2-methylphenyl)(methylsulfonyl)amino]butanoic acid MFCD28954544 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.
