Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 311.81 g/mol gives Sodium 1-((4-ethoxy-4-oxobutanoyl)oxy)dodecane-2-sulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Sodium 1-((4-ethoxy-4-oxobutanoyl)oxy)dodecane-2-sulfonate (CAS 103900-46-5), a certified reference material (molecular formula C16H21NO3HCl, MW 311.81 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Sodium 1-((4-ethoxy-4-oxobutanoyl)oxy)dodecane-2-sulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 311.81 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
