Chemical Structure
Description
CATO supplies 2-Propenoic acid, 2-methyl-, telomer with sodium sulfite (1:1), sodium salt (CAS 156559-16-9), a certified reference material (molecular formula HNaO3SC4H6O2Na, MW 213.13 g/mol) for analytical method development and quality control.
Based on its molecular formula HNaO3SC4H6O2Na, 2-Propenoic acid, 2-methyl-, telomer with sodium sulfite (1:1), sodium salt contains a carbohydrate-derived structure, a sulfone group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 213.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
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.
