Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 551.61 g/mol gives p-SCN-Bn-DOTA distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
p-SCN-Bn-DOTA (CAS 127985-74-4) is a high-purity analytical reference standard with the molecular formula C24H33N5O8S and a molecular weight of 551.61 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, p-SCN-Bn-DOTA is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 551.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
