Basic Blue 20 CAS 82-94-0

Description

Compared with other compounds in its class, the molecular weight of 423.02 g/mol gives Basic Blue 20 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Basic Blue 20 (CAS 82-94-0) is a high-purity analytical reference standard with the molecular formula C26H33N3Cl and a molecular weight of 423.02 g/mol.

Basic Blue 20 (C26H33N3Cl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.

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.
