9,10-Dioxo-9,10-dihydroanthracene-1-carboxamide CAS 7223-68-9

Description

As a certified reference material (CRM), 9,10-Dioxo-9,10-dihydroanthracene-1-carboxamide 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.

9,10-Dioxo-9,10-dihydroanthracene-1-carboxamide (CAS 7223-68-9), molecular formula C15H9NO3 and molecular weight 251.24 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 9,10-Dioxo-9,10-dihydroanthracene-1-carboxamide (C15H9NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 251.24 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.
