Chemical Structure
Description
3-(3,5-Dichlorophenoxy)propane-1-sulfonyl chloride (CAS 1018271-86-7), molecular formula C9H9Cl3O3S and molecular weight 303.59 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(3,5-Dichlorophenoxy)propane-1-sulfonyl chloride (C9H9Cl3O3S) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
