Description
CATO manufactures 4-methoxy-2-methylbenzene-1-sulfonyl chloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
4-methoxy-2-methylbenzene-1-sulfonyl chloride (CAS 68978-27-8) is a high-purity analytical reference standard with the molecular formula C8H15ClO3S and a molecular weight of 226.72 g/mol.
The molecular framework of 4-methoxy-2-methylbenzene-1-sulfonyl chloride (C8H15ClO3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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. 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.
