Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 262.76 g/mol gives 5-Amino-2-chloro-N,N-diethylbenzene-1-sulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Amino-2-chloro-N,N-diethylbenzene-1-sulfonamide (CAS 571150-08-8), molecular formula C10H15ClN2O2S and molecular weight 262.76 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Amino-2-chloro-N,N-diethylbenzene-1-sulfonamide (C10H15ClN2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
