Compared with other compounds in its class, the molecular weight of 5916.82 g/mol gives Insulin Detemir distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Insulin Detemir (CAS 169148-63-4) is a high-purity analytical reference standard with the molecular formula C267H402N64O76S6 and a molecular weight of 5916.82 g/mol.
Insulin Detemir (C267H402N64O76S6) contains a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
