Chemical Structure

N-tert-butylpyridine-3-sulfonamide CAS 17432-06-3 chemical structure

Description

Structurally, N-tert-butylpyridine-3-sulfonamide (C9H20N2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 220.33 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.

N-tert-butylpyridine-3-sulfonamide (CAS 17432-06-3), molecular formula C9H20N2O2S and molecular weight 220.33 g/mol, is a CATO reference standard with documented purity and traceability.

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.
