Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(2-Iodo-5-methoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1256781-69-7) is a high-purity analytical reference standard with the molecular formula C13H18BIO3 and a molecular weight of 360.00 g/mol.
Structurally, 2-(2-Iodo-5-methoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C13H18BIO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 360.00 g/mol, it falls into the moderately-high-molecular-weight range. 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.
