Chemical Structure
Description
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.
2-((1-(Thiophen-2-yl)ethylidene)amino)ethanesulfonic acid (CAS 141096-82-4), molecular formula C8H11NO3S2 and molecular weight 233.31 g/mol, is a CATO reference standard with documented purity and traceability.
2-((1-(Thiophen-2-yl)ethylidene)amino)ethanesulfonic acid (C8H11NO3S2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 2-((1-(Thiophen-2-yl)ethylidene)amino)ethanesulfonic acid 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.
