Chemical Structure

Phenyl β-D-thiogalactopyranoside CAS 16758-34-2 chemical structure

Description

The occurrence of Phenyl β-D-thiogalactopyranoside is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Phenyl β-D-thiogalactopyranoside (CAS 16758-34-2) is a high-purity analytical reference standard with the molecular formula C12H16O5S and a molecular weight of 272.32 g/mol.

Based on its molecular formula C12H16O5S, Phenyl β-D-thiogalactopyranoside contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 272.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
