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.
Tetramethylammonium hydrogen sulfate xhydrate (CAS 207738-07-6), molecular formula HO4SC4H12NH2O and molecular weight 189.23 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Tetramethylammonium hydrogen sulfate xhydrate (HO4SC4H12NH2O) contains a carbohydrate-derived structure, an amide group, a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of -2.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 189.23 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
