Chemical Structure
Description
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.
CATO supplies 4-[(3,4-Dichloro-1-methyl-1H-pyrazol-5-yl)oxy]-N-tridecylbenzene-1-sulfonamide (CAS 318284-30-9), a certified reference material (molecular formula C23H35Cl2N3O3S, MW 504.51 g/mol) for analytical method development and quality control.
The molecular framework of 4-[(3,4-Dichloro-1-methyl-1H-pyrazol-5-yl)oxy]-N-tridecylbenzene-1-sulfonamide (C23H35Cl2N3O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).
As a certified reference material (CRM), 4-[(3,4-Dichloro-1-methyl-1H-pyrazol-5-yl)oxy]-N-tridecylbenzene-1-sulfonamide 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.
