Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 154.23 g/mol gives O-[(methylthio)methyl]phenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies O-[(methylthio)methyl]phenol (CAS 4526-41-4), a certified reference material (molecular formula C8H10OS, MW 154.23 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, O-[(methylthio)methyl]phenol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 154.23 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), O-[(methylthio)methyl]phenol 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.
