Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1H,3h-isochromeno[6,5,4-mna]xanthene-1,3-dione.
1H,3h-isochromeno[6,5,4-mna]xanthene-1,3-dione (CAS 36310-05-1), molecular formula C18H8O4 and molecular weight 288.25 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1H,3h-isochromeno[6,5,4-mna]xanthene-1,3-dione (C18H8O4) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 288.25 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 1H,3h-isochromeno[6,5,4-mna]xanthene-1,3-dione 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.
