Chemical Structure

4-Iodo-N-hydroxybenzamide CAS 2593-31-9 chemical structure

Description

The occurrence of 4-Iodo-N-hydroxybenzamide is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Iodo-N-hydroxybenzamide (CAS 2593-31-9) is a high-purity analytical reference standard with the molecular formula C7H6INO2 and a molecular weight of 263.03 g/mol.

Structurally, 4-Iodo-N-hydroxybenzamide (C7H6INO2) contains an amide group, a carboxylic acid group, 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 263.03 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.

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-N-hydroxybenzamide 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.
