Chemical Structure
Description
As a certified reference material (CRM), 5-(tert-Butyl)-2-cyclopropoxybenzenesulfonamide 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.
5-(tert-Butyl)-2-cyclopropoxybenzenesulfonamide (CAS 1243345-55-2), molecular formula C13H19NO3S and molecular weight 269.36 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(tert-Butyl)-2-cyclopropoxybenzenesulfonamide (C13H19NO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
