Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Sodium 1-hydroxycyclopentane-1-sulfonate (CAS 6950-56-7), molecular formula C5H10O4SNa and molecular weight 189.18 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5H10O4SNa, Sodium 1-hydroxycyclopentane-1-sulfonate 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 189.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
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.
