Chemical Structure
Description
CATO supplies 1-(2-Chloro-4-methyl-5-(methylsulfonyl)phenyl)piperazine (CAS 849035-65-0), a certified reference material (molecular formula C12H17ClN2O2S, MW 288.79 g/mol) for analytical method development and quality control.
1-(2-Chloro-4-methyl-5-(methylsulfonyl)phenyl)piperazine (C12H17ClN2O2S) 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.
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.
