Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Bromo-N-(3-methoxypropyl)-3-methylbenzenesulfonamide (CAS 1003740-55-3) is a high-purity analytical reference standard with the molecular formula C11H16BrNO3S and a molecular weight of 322.22 g/mol.
The molecular framework of 4-Bromo-N-(3-methoxypropyl)-3-methylbenzenesulfonamide (C11H16BrNO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 4-Bromo-N-(3-methoxypropyl)-3-methylbenzenesulfonamide 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.
