Chemical Structure
Description
The occurrence of N-(5-Iodopyridin-2-yl)-2-{[(E)-[3-(4-methylphenyl)-3-oxopropylidene]amino]oxy}acetamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(5-Iodopyridin-2-yl)-2-{[(E)-[3-(4-methylphenyl)-3-oxopropylidene]amino]oxy}acetamide (CAS 339018-03-0), molecular formula C17H16IN3O3 and molecular weight 437.23 g/mol, is a CATO reference standard with documented purity and traceability.
N-(5-Iodopyridin-2-yl)-2-{[(E)-[3-(4-methylphenyl)-3-oxopropylidene]amino]oxy}acetamide (C17H16IN3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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), N-(5-Iodopyridin-2-yl)-2-{[(E)-[3-(4-methylphenyl)-3-oxopropylidene]amino]oxy}acetamide 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.
