Chemical Structure
Description
1-((4-Nitrophenyl)thio)propan-2-one (CAS 25784-85-4), molecular formula C9H9NO3S and molecular weight 211.24 g/mol, is a CATO reference standard with documented purity and traceability.
1-((4-Nitrophenyl)thio)propan-2-one (C9H9NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 1-((4-Nitrophenyl)thio)propan-2-one 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.
