3-(Phenylthio)propane-1,2-diol CAS 5149-48-4

Description

Compared with other compounds in its class, the molecular weight of 184.26 g/mol gives 3-(Phenylthio)propane-1,2-diol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-(Phenylthio)propane-1,2-diol (CAS 5149-48-4) is a high-purity analytical reference standard with the molecular formula C9H12O2S and a molecular weight of 184.26 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 3-(Phenylthio)propane-1,2-diol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 184.26 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), 3-(Phenylthio)propane-1,2-diol 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.
