2-Iodo-4,5-dimethoxybenzoic acid CAS 61203-48-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Iodo-4,5-dimethoxybenzoic acid.

2-Iodo-4,5-dimethoxybenzoic acid (CAS 61203-48-3), molecular formula C9H9IO4 and molecular weight 308.07 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Iodo-4,5-dimethoxybenzoic acid (C9H9IO4) contains 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 308.07 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 2-Iodo-4,5-dimethoxybenzoic 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.
