Chemical Structure
Description
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.
CATO supplies 8-bromo-3-iodo-naphthalene-1-carboxylic acid (CAS 2387597-87-5), a certified reference material (molecular formula C11H16BrIO2, MW 387.05 g/mol) for analytical method development and quality control.
Structurally, 8-bromo-3-iodo-naphthalene-1-carboxylic acid (C11H16BrIO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine/iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 387.05 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).
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.
