Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 635.32 g/mol gives 5-(2-Chloroacetamido)-2,4,6-triiodo-isophthalic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-(2-Chloroacetamido)-2,4,6-triiodo-isophthalic Acid (CAS 4873-45-4) is a high-purity analytical reference standard with the molecular formula C10H5ClI3NO5 and a molecular weight of 635.32 g/mol.
The molecular framework of 5-(2-Chloroacetamido)-2,4,6-triiodo-isophthalic Acid (C10H5ClI3NO5) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
