Chemical Structure
Description
21-Hydroxy-5,8,11,14,17-pentaoxahenicosyl 4-methylbenzenesulfonate (CAS 2681388-13-4) is a high-purity analytical reference standard with the molecular formula C23H40O9S and a molecular weight of 492.62 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 21-Hydroxy-5,8,11,14,17-pentaoxahenicosyl 4-methylbenzenesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 492.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 21-Hydroxy-5,8,11,14,17-pentaoxahenicosyl 4-methylbenzenesulfonate 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.
