n-(2-(5-Bromothiophen-2-yl)ethyl)-3-methylbut-2-enamide (CAS 1223743-13-2), molecular formula C11H14BrNOS and molecular weight 288.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of n-(2-(5-Bromothiophen-2-yl)ethyl)-3-methylbut-2-enamide (C11H14BrNOS) 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.
