Description
CATO supplies 2,6-Bis(4-azidobenzylidene)cyclohexanone (wetted with ca. 30% Water) (unit weight on dry weight basis) [Research for Photosensitive Material] (CAS 20237-98-3), a certified reference material (molecular formula C20H16N6O, MW 356.38 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2,6-Bis(4-azidobenzylidene)cyclohexanone (wetted with ca. 30% Water) (unit weight on dry weight basis) [Research for Photosensitive Material] is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 356.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
