854860-48-3 2,5-Dimethyl-4-nitrobenzene-1-sulfonyl chloride MFCD19200434 CAS 854860-48-3 chemical structure

Description

The occurrence of 854860-48-3 2,5-Dimethyl-4-nitrobenzene-1-sulfonyl chloride MFCD19200434 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

854860-48-3 2,5-Dimethyl-4-nitrobenzene-1-sulfonyl chloride MFCD19200434 (CAS 854860-48-3), molecular formula C8H8ClNO4S and molecular weight 249.67 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 854860-48-3 2,5-Dimethyl-4-nitrobenzene-1-sulfonyl chloride MFCD19200434 (C8H8ClNO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 249.67 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.
