Chemical Structure

2,4,6-tritert-butylbenzenesulfonic acid CAS 151252-78-7 chemical structure

Description

As a certified reference material (CRM), 2,4,6-tritert-butylbenzenesulfonic acid 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.

CATO supplies 2,4,6-tritert-butylbenzenesulfonic acid (CAS 151252-78-7), a certified reference material (molecular formula C18H30O3S, MW 326.49 g/mol) for analytical method development and quality control.

Structurally, 2,4,6-tritert-butylbenzenesulfonic acid (C18H30O3S) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 326.49 g/mol, it falls into the moderately-high-molecular-weight range. 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.
