Chemical Structure

Tetrahydro-2H-thiopyran-2-carboxylic Acid CAS 53916-77-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 146.21 g/mol gives Tetrahydro-2H-thiopyran-2-carboxylic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Tetrahydro-2H-thiopyran-2-carboxylic Acid (CAS 53916-77-1) is a high-purity analytical reference standard with the molecular formula C6H10O2S and a molecular weight of 146.21 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Tetrahydro-2H-thiopyran-2-carboxylic Acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.

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.
