Chemical Structure
Description
[Tyr52, Asn76] Parathyroid Hormone (52-84), human (C158H265N49O43) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
[Tyr52, Asn76] Parathyroid Hormone (52-84), human (CAS 89492-47-7) is a high-purity analytical reference standard with the molecular formula C158H265N49O43 and a molecular weight of 3539.10 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
