Chemical Structure
Description
The occurrence of 2-(Pyridazin-3-yl)acetonitrile is closely related to a nitrile group, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(Pyridazin-3-yl)acetonitrile (CAS 27349-80-0), molecular formula C6H5N3 and molecular weight 119.12 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, an aromatic ring system, 2-(Pyridazin-3-yl)acetonitrile is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 119.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
