Chemical Structure
Description
The occurrence of 31098-20-1 Potassium 3-sulphonatopropyl acrylate 2-Propenoic acid, 3-sulfopropyl ester, potassium salt (1:1) 2-Propenoic acid, 3-sulfopropyl ester, potassium salt EINECS 250-465-0 EC 250-465-0 is closely related to a carbohydrate-derived structure, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 31098-20-1 Potassium 3-sulphonatopropyl acrylate 2-Propenoic acid, 3-sulfopropyl ester, potassium salt (1:1) 2-Propenoic acid, 3-sulfopropyl ester, potassium salt EINECS 250-465-0 EC 250-465-0 (CAS 31098-20-1), a certified reference material (molecular formula C6H9O5SK, MW 232.29 g/mol) for analytical method development and quality control.
The molecular framework of 31098-20-1 Potassium 3-sulphonatopropyl acrylate 2-Propenoic acid, 3-sulfopropyl ester, potassium salt (1:1) 2-Propenoic acid, 3-sulfopropyl ester, potassium salt EINECS 250-465-0 EC 250-465-0 (C6H9O5SK) is characterized by a carbohydrate-derived structure, a sulfone group. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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.
