3,6-dihydro-2H-1$l^{6}-thiopyran-1,1-dione CAS 16841-46-6

Description

The occurrence of 3,6-dihydro-2H-1$l^{6}-thiopyran-1,1-dione is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3,6-dihydro-2H-1$l^{6}-thiopyran-1,1-dione (CAS 16841-46-6), molecular formula C5H8O2S and molecular weight 132.18 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3,6-dihydro-2H-1$l^{6}-thiopyran-1,1-dione (C5H8O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 132.18 g/mol, it falls into the low-molecular-weight range.

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.
