Chemical Structure
Description
The occurrence of 3759-28-2 alpha,o-Toluenedicarbonitrile o-Tolunitrile, alpha-cyano- Benzeneacetonitrile, 2-cyano- 2-Cyanobenzeneacetonitrile o-Cyanobenzyl cyanide 2-Cyanobenzyl cyanide (o-Cyanophenyl)acetonitrile alpha-Cyano-o-tolunitrile EINECS 223-167-3 Homophthalonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3759-28-2 alpha,o-Toluenedicarbonitrile o-Tolunitrile, alpha-cyano- Benzeneacetonitrile, 2-cyano- 2-Cyanobenzeneacetonitrile o-Cyanobenzyl cyanide 2-Cyanobenzyl cyanide (o-Cyanophenyl)acetonitrile alpha-Cyano-o-tolunitrile EINECS 223-167-3 Homophthalonitrile (CAS 3759-28-2) is a high-purity analytical reference standard with the molecular formula C9H12N2 and a molecular weight of 148.20 g/mol.
Based on its molecular formula C9H12N2, 3759-28-2 alpha,o-Toluenedicarbonitrile o-Tolunitrile, alpha-cyano- Benzeneacetonitrile, 2-cyano- 2-Cyanobenzeneacetonitrile o-Cyanobenzyl cyanide 2-Cyanobenzyl cyanide (o-Cyanophenyl)acetonitrile alpha-Cyano-o-tolunitrile EINECS 223-167-3 Homophthalonitrile contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 148.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
