Chemical Structure
Description
(E)-Methyl 4-((2-((2-(trifluoromethyl)phenyl)sulfonyl)hydrazono)methyl)benzoate (CAS 2301998-81-0), molecular formula C16H13F3N2O4S and molecular weight 386.35 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (E)-Methyl 4-((2-((2-(trifluoromethyl)phenyl)sulfonyl)hydrazono)methyl)benzoate (C16H13F3N2O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 386.35 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
