Description

Compared with other compounds in its class, the molecular weight of 275.26 g/mol gives Sodium 3-(5-imino-3-methyl-4,5-dihydro-1H-pyrazol-1-yl)benzenesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Sodium 3-(5-imino-3-methyl-4,5-dihydro-1H-pyrazol-1-yl)benzenesulfonate (CAS 83949-49-9), molecular formula C10H10N3O3SNa and molecular weight 275.26 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Sodium 3-(5-imino-3-methyl-4,5-dihydro-1H-pyrazol-1-yl)benzenesulfonate (C10H10N3O3SNa) 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 7.5, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 275.26 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
