Description
CATO supplies 4-(1,3-Dithiolan-2-yl)phenyl 2,3,4,5,6-pentamethylbenzene-1-sulfonate (CAS 301193-54-4), a certified reference material (molecular formula C20H24O3S3, MW 408.60 g/mol) for analytical method development and quality control.
Structurally, 4-(1,3-Dithiolan-2-yl)phenyl 2,3,4,5,6-pentamethylbenzene-1-sulfonate (C20H24O3S3) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 408.60 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
As a certified reference material (CRM), 4-(1,3-Dithiolan-2-yl)phenyl 2,3,4,5,6-pentamethylbenzene-1-sulfonate 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.
