Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Iobitridol Impurity 9.
Iobitridol Impurity 9 (CAS 342892-07-3) is a certified pharmaceutical impurity reference standard with the molecular formula C10H18O4 and a molecular weight of 202.25 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Iobitridol Impurity 9 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
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.
