Compared with other compounds in its class, the molecular weight of 366.19 g/mol gives 3,5-Dimethyl-3-iodo-4-methoxybenzophenone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3,5-Dimethyl-3-iodo-4-methoxybenzophenone (CAS 951884-47-2), a certified reference material (molecular formula C16H15IO2, MW 366.19 g/mol) for analytical method development and quality control.
Structurally, 3,5-Dimethyl-3-iodo-4-methoxybenzophenone (C16H15IO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 366.19 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
