2,4-Diiodo-6-formylphenol 2-hydroxy-3,5-diiodobenzaldehyde 2631-77-8 3,5-Diiodosalicylaldehyde CAS 2631-77-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,4-Diiodo-6-formylphenol 2-hydroxy-3,5-diiodobenzaldehyde 2631-77-8 3,5-Diiodosalicylaldehyde.

CATO supplies 2,4-Diiodo-6-formylphenol 2-hydroxy-3,5-diiodobenzaldehyde 2631-77-8 3,5-Diiodosalicylaldehyde (CAS 2631-77-8), a certified reference material (molecular formula C7H10I2O2, MW 379.96 g/mol) for analytical method development and quality control.

Based on its molecular formula C7H10I2O2, 2,4-Diiodo-6-formylphenol 2-hydroxy-3,5-diiodobenzaldehyde 2631-77-8 3,5-Diiodosalicylaldehyde contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 379.96 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

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.
