Chemical Structure
Description
The occurrence of 2-Iodo-1,2,3,4-tetrahydronaphthalene is closely related to iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Iodo-1,2,3,4-tetrahydronaphthalene (CAS 117408-86-3) is a high-purity analytical reference standard with the molecular formula C10H11I and a molecular weight of 258.10 g/mol.
The molecular framework of 2-Iodo-1,2,3,4-tetrahydronaphthalene (C10H11I) is characterized by iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
