Chemical Structure
Description
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.
3-(2,3,3-trimethyl-5-sulfo-3H-indol-1-ium-1-yl)propane-1-sulfonate, potassium salt (CAS 427882-78-8), molecular formula C14H19NO6S2K and molecular weight 400.52 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(2,3,3-trimethyl-5-sulfo-3H-indol-1-ium-1-yl)propane-1-sulfonate, potassium salt (C14H19NO6S2K) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 400.52 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
