Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-N-(4-(2-Chloro-1-hydroxyethyl)phenyl)-N-methylmethanesulfonamide.
(S)-N-(4-(2-Chloro-1-hydroxyethyl)phenyl)-N-methylmethanesulfonamide (CAS 1175768-76-9) is a high-purity analytical reference standard with the molecular formula C10H14ClNO3S and a molecular weight of 263.74 g/mol.
(S)-N-(4-(2-Chloro-1-hydroxyethyl)phenyl)-N-methylmethanesulfonamide (C10H14ClNO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), (S)-N-(4-(2-Chloro-1-hydroxyethyl)phenyl)-N-methylmethanesulfonamide 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.
