(3-Iodo-5-methylphenyl)methanol CAS 937638-61-4 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

(3-Iodo-5-methylphenyl)methanol (CAS 937638-61-4), molecular formula C8H9IO and molecular weight 248.06 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H9IO, (3-Iodo-5-methylphenyl)methanol contains a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 248.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
