Chemical Structure
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.
924859-49-4 Ethyl 2,4-dichloro-5-(chlorosulfonyl)benzoate MFCD11057851 (CAS 924859-49-4), molecular formula C9H7Cl3O4S and molecular weight 317.57 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 924859-49-4 Ethyl 2,4-dichloro-5-(chlorosulfonyl)benzoate MFCD11057851 (C9H7Cl3O4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 924859-49-4 Ethyl 2,4-dichloro-5-(chlorosulfonyl)benzoate MFCD11057851 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.
