Description

CATO manufactures 5-(4-Methanesulfonylphenyl)-2-methyl-3-[(1Z)-2,2,2-trifluoro-1-[2-(4-methylphenyl)hydrazin-1-ylidene]ethyl]-1-[3-(trifluoromethyl)phenyl]-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.

5-(4-Methanesulfonylphenyl)-2-methyl-3-[(1Z)-2,2,2-trifluoro-1-[2-(4-methylphenyl)hydrazin-1-ylidene]ethyl]-1-[3-(trifluoromethyl)phenyl]-1H-pyrrole (CAS 478043-34-4) is a high-purity analytical reference standard with the molecular formula C28H23F6N3O2S and a molecular weight of 579.56 g/mol.

5-(4-Methanesulfonylphenyl)-2-methyl-3-[(1Z)-2,2,2-trifluoro-1-[2-(4-methylphenyl)hydrazin-1-ylidene]ethyl]-1-[3-(trifluoromethyl)phenyl]-1H-pyrrole (C28H23F6N3O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
