Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1393-88-0 Gramicidin D EINECS 215-738-0 Gramicidina D Gramicidin Dubos (CAS 1393-88-0) is a high-purity analytical reference standard with the molecular formula C96H135N19O16 and a molecular weight of 1811.22 g/mol.
The molecular framework of 1393-88-0 Gramicidin D EINECS 215-738-0 Gramicidina D Gramicidin Dubos (C96H135N19O16) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
