Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 999.12 g/mol gives [Asu1,6,Arg8] Vasotocin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies [Asu1,6,Arg8] Vasotocin (CAS 35375-13-4), a certified reference material (molecular formula C45H70N14O12, MW 999.12 g/mol) for analytical method development and quality control.
[Asu1,6,Arg8] Vasotocin (C45H70N14O12) contains a nitrogen-containing heterocyclic scaffold, an amide 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.
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.
