Chemical Structure
Description
As a certified reference material (CRM), N-[3-(azepane-1-sulfonyl)-4-methylphenyl]-2-chloroacetamide 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.
N-[3-(azepane-1-sulfonyl)-4-methylphenyl]-2-chloroacetamide (CAS 379255-23-9), molecular formula C15H21ClN2O3S and molecular weight 344.86 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, N-[3-(azepane-1-sulfonyl)-4-methylphenyl]-2-chloroacetamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 344.86 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
