Description

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.

2,4-DICHLORO-1-[ISOCYANO-(TOLUENE-4-SULFONYL)-METHYL]-BENZENE 2,4-dichloro-1-(isocyano(tosyl)methyl)benzene 952727-77-4 (CAS 952727-77-4) is a high-purity analytical reference standard with the molecular formula C15H11Cl2NO2S and a molecular weight of 340.22 g/mol.

Structurally, 2,4-DICHLORO-1-[ISOCYANO-(TOLUENE-4-SULFONYL)-METHYL]-BENZENE 2,4-dichloro-1-(isocyano(tosyl)methyl)benzene 952727-77-4 (C15H11Cl2NO2S) 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 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 340.22 g/mol, it falls into the moderately-high-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).

As a certified reference material (CRM), 2,4-DICHLORO-1-[ISOCYANO-(TOLUENE-4-SULFONYL)-METHYL]-BENZENE 2,4-dichloro-1-(isocyano(tosyl)methyl)benzene 952727-77-4 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
