Tetrahydro-2H-thiopyran-4-carbonyl chloride 1,1-dioxide CAS 841301-53-9

Description

Compared with other compounds in its class, the molecular weight of 196.65 g/mol gives Tetrahydro-2H-thiopyran-4-carbonyl chloride 1,1-dioxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Tetrahydro-2H-thiopyran-4-carbonyl chloride 1,1-dioxide (CAS 841301-53-9), molecular formula C6H9ClO3S and molecular weight 196.65 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Tetrahydro-2H-thiopyran-4-carbonyl chloride 1,1-dioxide (C6H9ClO3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
