5-Iodo-3,4-dihydronaphthalen-1(2H)-one CAS 1199782-87-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Iodo-3,4-dihydronaphthalen-1(2H)-one.

5-Iodo-3,4-dihydronaphthalen-1(2H)-one (CAS 1199782-87-0) is a high-purity analytical reference standard with the molecular formula C10H9IO and a molecular weight of 272.08 g/mol.

Owing to a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system, 5-Iodo-3,4-dihydronaphthalen-1(2H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 272.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
