Chemical Structure
Description
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.
(2-Methyl-4-(4-methylpiperazin-1-yl)phenyl)boronic acid (CAS 2159136-21-5) is a high-purity analytical reference standard with the molecular formula C12H19BN2O2 and a molecular weight of 234.10 g/mol.
Structurally, (2-Methyl-4-(4-methylpiperazin-1-yl)phenyl)boronic acid (C12H19BN2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 234.10 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
