Chemical Structure
Description
The occurrence of (Asn10,Leu11,D-Trp12)-pTH-Related Protein (7-34) amide (human, mouse, rat) trifluoroacetate salt is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(Asn10,Leu11,D-Trp12)-pTH-Related Protein (7-34) amide (human, mouse, rat) trifluoroacetate salt (CAS 129622-68-0), molecular formula C162H254N50O36 and molecular weight 3478.06 g/mol, is a CATO reference standard with documented purity and traceability.
(Asn10,Leu11,D-Trp12)-pTH-Related Protein (7-34) amide (human, mouse, rat) trifluoroacetate salt (C162H254N50O36) 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.
