Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(4-((2-(4-Chlorophenylsulfonamido)ethyl)thio)-2,6-difluorophenoxy)acetic acid (CAS 141286-14-8), molecular formula C16H14ClF2NO5S2 and molecular weight 437.87 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(4-((2-(4-Chlorophenylsulfonamido)ethyl)thio)-2,6-difluorophenoxy)acetic acid (C16H14ClF2NO5S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 437.87 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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.
