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 N,N,4,6-tetramethyl-3-(o-tolylsulfonyl)pyridin-2-amine.
N,N,4,6-tetramethyl-3-(o-tolylsulfonyl)pyridin-2-amine (CAS 338774-40-6) is a high-purity analytical reference standard with the molecular formula C16H20N2O2S and a molecular weight of 304.41 g/mol.
N,N,4,6-tetramethyl-3-(o-tolylsulfonyl)pyridin-2-amine (C16H20N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
CATO manufactures N,N,4,6-tetramethyl-3-(o-tolylsulfonyl)pyridin-2-amine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
