Description
As a certified reference material (CRM), 2,4,6-triethylbenzene-1-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.
2,4,6-triethylbenzene-1-sulfonyl chloride (CAS 115472-98-5), molecular formula C12H17ClO2S and molecular weight 260.78 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,4,6-triethylbenzene-1-sulfonyl chloride (C12H17ClO2S) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
