7-((4-Ethynylphenyl)ethynyl)-5,5-difluoro-N,N-bis(2-(phenylselanyl)ethyl)-10-(p-tolyl)-5H-4l4,5l4-dipyrrolo[1,2-c:2',1'-f][1,3,2]diazaborinin-3-amine CAS 1962170-57-5

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.

7-((4-Ethynylphenyl)ethynyl)-5,5-difluoro-N,N-bis(2-(phenylselanyl)ethyl)-10-(p-tolyl)-5H-4l4,5l4-dipyrrolo[1,2-c:2',1'-f][1,3,2]diazaborinin-3-amine (CAS 1962170-57-5) is a high-purity analytical reference standard with the molecular formula C42H34BF2N3Se2 and a molecular weight of 787.47 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, 7-((4-Ethynylphenyl)ethynyl)-5,5-difluoro-N,N-bis(2-(phenylselanyl)ethyl)-10-(p-tolyl)-5H-4l4,5l4-dipyrrolo[1,2-c:2',1'-f][1,3,2]diazaborinin-3-amine is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 787.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
