Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 160822-47-9 4-(3-Methylanilino)pyridine-3-sulfonamide--hydrogen chloride (1/1) DTXSID60695739.
160822-47-9 4-(3-Methylanilino)pyridine-3-sulfonamide--hydrogen chloride (1/1) DTXSID60695739 (CAS 160822-47-9) is a high-purity analytical reference standard with the molecular formula C12H13N3O2SHCl and a molecular weight of 299.77 g/mol.
Structurally, 160822-47-9 4-(3-Methylanilino)pyridine-3-sulfonamide--hydrogen chloride (1/1) DTXSID60695739 (C12H13N3O2SHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 299.77 g/mol, it falls into the medium-molecular-weight range. 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.
