Chemical Structure
Description
Based on its molecular formula C11H17IO2, 3-iodonaphthalene-1-carboxylic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 308.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
3-iodonaphthalene-1-carboxylic acid (CAS 91059-40-4) is a high-purity analytical reference standard with the molecular formula C11H17IO2 and a molecular weight of 308.16 g/mol.
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), 3-iodonaphthalene-1-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.
