Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 390.86 g/mol gives Sclerotiorin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Sclerotiorin (CAS 549-23-5), a certified reference material (molecular formula C21H23ClO5, MW 390.86 g/mol) for analytical method development and quality control.
Based on its molecular formula C21H23ClO5, Sclerotiorin contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 390.86 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), Sclerotiorin meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
