21205-91-4 9-BBN dimer MFCD00168069 9-Borabicyclo[3.3.1]nonane dimer CAS 21205-91-4 chemical structure

Description

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.

21205-91-4 9-BBN dimer MFCD00168069 9-Borabicyclo[3.3.1]nonane dimer (CAS 21205-91-4) is a high-purity analytical reference standard with the molecular formula C16H28B2 and a molecular weight of 242.02 g/mol.

Structurally, 21205-91-4 9-BBN dimer MFCD00168069 9-Borabicyclo[3.3.1]nonane dimer (C16H28B2) contains an organic framework. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 242.02 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
