Chemical Structure
Description
As a certified reference material (CRM), 2-acetyl-2,3-dihydro-1H-isoindole-5-sulfonyl chloride 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.
2-acetyl-2,3-dihydro-1H-isoindole-5-sulfonyl chloride (CAS 1306607-01-1), molecular formula C10H10ClNO3S and molecular weight 259.71 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-acetyl-2,3-dihydro-1H-isoindole-5-sulfonyl chloride (C10H10ClNO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
