Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 477.55 g/mol gives Butorphanol Tartrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Butorphanol Tartrate (CAS 58786-99-5), molecular formula C21H29NO2C4H6O6 and molecular weight 477.55 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C21H29NO2C4H6O6, Butorphanol Tartrate contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 477.55 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
