Description

Compared with other compounds in its class, the molecular weight of 313.09 g/mol gives 4-Iodo-2-methylquinoline-6-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Iodo-2-methylquinoline-6-carboxylic acid (CAS 1261783-98-5), molecular formula C11H8INO2 and molecular weight 313.09 g/mol, is a CATO reference standard with documented purity and traceability.

4-Iodo-2-methylquinoline-6-carboxylic acid (C11H8INO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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

As a certified reference material (CRM), 4-Iodo-2-methylquinoline-6-carboxylic acid 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.
