Chemical Structure
Description
The occurrence of Pitavastatin Calcium Pentahydrate - API Standards is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Pitavastatin Calcium Pentahydrate - API Standards (CAS 1852536-33-4), a certified reference material (molecular formula C25H23FNO4CaH2O, MW 478.55 g/mol) for analytical method development and quality control.
Structurally, Pitavastatin Calcium Pentahydrate - API Standards (C25H23FNO4CaH2O) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.5, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 478.55 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
