Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-(2-Chlorophenyl)-4-(methylsulfonyl)-1H-pyrrole (CAS 87388-63-4), molecular formula C11H10ClNO2S and molecular weight 255.72 g/mol, is a CATO reference standard with documented purity and traceability.
3-(2-Chlorophenyl)-4-(methylsulfonyl)-1H-pyrrole (C11H10ClNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
CATO manufactures 3-(2-Chlorophenyl)-4-(methylsulfonyl)-1H-pyrrole 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.
