Chemical Structure
Description
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.
CATO supplies 4-Oxo-2-(tetrahydro-2H-pyran-4-yl)chroman-6-sulfonyl chloride (CAS 2230779-85-6), a certified reference material (molecular formula C14H15ClO5S, MW 330.78 g/mol) for analytical method development and quality control.
The molecular framework of 4-Oxo-2-(tetrahydro-2H-pyran-4-yl)chroman-6-sulfonyl chloride (C14H15ClO5S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. 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.
