Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((5-(2-(Phenylsulfonamido)ethyl)thiophen-2-yl)oxy)acetic acid.
2-((5-(2-(Phenylsulfonamido)ethyl)thiophen-2-yl)oxy)acetic acid (CAS 120824-08-0), molecular formula C14H15NO5S2 and molecular weight 341.40 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-((5-(2-(Phenylsulfonamido)ethyl)thiophen-2-yl)oxy)acetic acid (C14H15NO5S2) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
