Chemical Structure
Description
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 4,4'-(Benzo[c][1,2,5]thiadiazole-4,7-diylbis(thiophene-5,2-diyl))diphenol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 484.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies 4,4'-(Benzo[c][1,2,5]thiadiazole-4,7-diylbis(thiophene-5,2-diyl))diphenol (CAS 925455-08-9), a certified reference material (molecular formula C26H16N2O2S3, MW 484.61 g/mol) for analytical method development and quality control.
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.
