Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-Iodo-3-methylphenyl)ethan-1-one.
CATO supplies 1-(4-Iodo-3-methylphenyl)ethan-1-one (CAS 52107-80-9), a certified reference material (molecular formula C9H9IO, MW 260.07 g/mol) for analytical method development and quality control.
Structurally, 1-(4-Iodo-3-methylphenyl)ethan-1-one (C9H9IO) contains a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 260.07 g/mol, it falls into the medium-molecular-weight range. 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.
As a certified reference material (CRM), 1-(4-Iodo-3-methylphenyl)ethan-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
