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 1YEO6NB5V5 34725-61-6 Sodium bromophenol Blue Bromophenol blue, sodium salt Phenol, 4,4'-(1,1-dioxido-3H-2,1-benzoxathiol-3-ylidene)bis(2,6-dibromo-, sodium salt (1:1) Phenol, 4,4'-(1,1-dioxido-3H-2,1-benzoxathiol-3-ylidene)bis(2,6-dibromo-, monosodium salt EINECS 252-170-2 UNII-1YEO6NB5V5 (CAS 34725-61-6), a certified reference material (molecular formula C19H21Br4O5SNa, MW 704.04 g/mol) for analytical method development and quality control.
Owing to a salt form, a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, 1YEO6NB5V5 34725-61-6 Sodium bromophenol Blue Bromophenol blue, sodium salt Phenol, 4,4'-(1,1-dioxido-3H-2,1-benzoxathiol-3-ylidene)bis(2,6-dibromo-, sodium salt (1:1) Phenol, 4,4'-(1,1-dioxido-3H-2,1-benzoxathiol-3-ylidene)bis(2,6-dibromo-, monosodium salt EINECS 252-170-2 UNII-1YEO6NB5V5 is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 704.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
