Chemical Structure
Description
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.
2-(4-Iodophenyl)-5,5-dimethyl-1,3,2-dioxaborinane (CAS 5572-94-1), molecular formula C11H14BIO2 and molecular weight 315.94 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(4-Iodophenyl)-5,5-dimethyl-1,3,2-dioxaborinane (C11H14BIO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
