Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 1995.31 g/mol gives Myelin Basic Protein (83-99) (bovine) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Myelin Basic Protein (83-99) (bovine) (CAS 178823-45-5), molecular formula C93H143N25O24 and molecular weight 1995.31 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Myelin Basic Protein (83-99) (bovine) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1995.31 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.
