Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (Met186)-Melanocyte Protein PMEL 17 (185-193) (human, bovine, mouse).
(Met186)-Melanocyte Protein PMEL 17 (185-193) (human, bovine, mouse) (CAS 181477-43-0) is a high-purity analytical reference standard with the molecular formula C47H74N10O14S and a molecular weight of 1035.23 g/mol.
(Met186)-Melanocyte Protein PMEL 17 (185-193) (human, bovine, mouse) (C47H74N10O14S) 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.
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.
