Description
As a certified reference material (CRM), 5,6-Dihydrobenzo[c]acridine-7-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.
5,6-Dihydrobenzo[c]acridine-7-carboxylic acid (CAS 83-93-2) is a high-purity analytical reference standard with the molecular formula C18H13NO2 and a molecular weight of 275.30 g/mol.
Structurally, 5,6-Dihydrobenzo[c]acridine-7-carboxylic acid (C18H13NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 275.30 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.
