Chemical Structure

(R)-2,3-Dihydroxypropyl 4-methylbenzenesulfonate CAS 41274-09-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 246.28 g/mol gives (R)-2,3-Dihydroxypropyl 4-methylbenzenesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (R)-2,3-Dihydroxypropyl 4-methylbenzenesulfonate (CAS 41274-09-3), a certified reference material (molecular formula C10H14O5S, MW 246.28 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, (R)-2,3-Dihydroxypropyl 4-methylbenzenesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 246.28 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), (R)-2,3-Dihydroxypropyl 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.
