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 S(-)-Cyanopindolol Hemifumarate Salt.
S(-)-Cyanopindolol Hemifumarate Salt (CAS 874882-72-1), molecular formula C16H21N3O2C4H4O4 and molecular weight 403.43 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C16H21N3O2C4H4O4, S(-)-Cyanopindolol Hemifumarate Salt contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 403.43 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
