Chemical Structure
Description
The occurrence of Lithium pyrrolidinoborohydride solution is closely related to an organic framework in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Lithium pyrrolidinoborohydride solution (CAS 144188-76-1), molecular formula C4H8BNLi and molecular weight 87.86 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Lithium pyrrolidinoborohydride solution (C4H8BNLi) is characterized by an organic framework. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
