(Z)-3-((4-bromothiophen-3-yl)methylene)indolin-2-one (CAS 900019-32-1), molecular formula C13H8BrNOS and molecular weight 306.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (Z)-3-((4-bromothiophen-3-yl)methylene)indolin-2-one (C13H8BrNOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
