Description
Compared with other compounds in its class, the molecular weight of 538.70 g/mol gives 12:0 N-Biotinyl fatty acid, NHS distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 12:0 N-Biotinyl fatty acid, NHS (CAS 216453-50-8), a certified reference material (molecular formula C26H42N4O6S, MW 538.70 g/mol) for analytical method development and quality control.
12:0 N-Biotinyl fatty acid, NHS (C26H42N4O6S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
