Chemical Structure
Description
The molecular framework of 3-Cyclopropoxy-5-(methylthio)isonicotinic acid (C10H11NO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
3-Cyclopropoxy-5-(methylthio)isonicotinic acid (CAS 1243321-22-3), molecular formula C10H11NO3S and molecular weight 225.26 g/mol, is a CATO reference standard with documented purity and traceability.
