Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 282.31 g/mol gives 6-AMidino-2-naphthol Methanesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 6-AMidino-2-naphthol Methanesulfonate (CAS 82957-06-0), a certified reference material (molecular formula C11H10N2OCH4O3S, MW 282.31 g/mol) for analytical method development and quality control.
Structurally, 6-AMidino-2-naphthol Methanesulfonate (C11H10N2OCH4O3S) 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 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 282.31 g/mol, it falls into the medium-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.
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.
