Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 366.85 g/mol gives PKI 166 hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
PKI 166 hydrochloride (CAS 2230253-82-2), molecular formula C20H18N4OHCl and molecular weight 366.85 g/mol, is a CATO reference standard with documented purity and traceability.
PKI 166 hydrochloride (C20H18N4OHCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
