Compared with other compounds in its class, the molecular weight of 292.35 g/mol gives 2-Phenoxyethyl 4-methylbenzenesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Phenoxyethyl 4-methylbenzenesulfonate (CAS 43224-81-3), a certified reference material (molecular formula C15H16O4S, MW 292.35 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, 2-Phenoxyethyl 4-methylbenzenesulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 292.35 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Phenoxyethyl 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.
