Description
Compared with other compounds in its class, the molecular weight of 231.29 g/mol gives 9-Anthracene-d9-carboxylic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
9-Anthracene-d9-carboxylic Acid (CAS 1219803-78-7) is a high-purity analytical reference standard with the molecular formula C15HD9O2 and a molecular weight of 231.29 g/mol.
Structurally, 9-Anthracene-d9-carboxylic Acid (C15HD9O2) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 15.5, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 231.29 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 9-Anthracene-d9-carboxylic Acid 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.
