Description
625-28-5 N2G72X091L Isovaleronitrile Butanenitrile, 3-methyl- 3-Methylbutyronitrile 4-02-00-00902 (Beilstein Handbook Reference) BRN 1734239 Butyronitrile, 3-methyl- EINECS 210-884-1 Isoamylnitrile Isobutyl cyanide Isopentane nitrile 2-Methylbutane secondary mononitrile NSC 148363 UNII-N2G72X091L (CAS 625-28-5) is a high-purity analytical reference standard with the molecular formula C5H9N and a molecular weight of 83.13 g/mol.
Owing to a nitrile group, 625-28-5 N2G72X091L Isovaleronitrile Butanenitrile, 3-methyl- 3-Methylbutyronitrile 4-02-00-00902 (Beilstein Handbook Reference) BRN 1734239 Butyronitrile, 3-methyl- EINECS 210-884-1 Isoamylnitrile Isobutyl cyanide Isopentane nitrile 2-Methylbutane secondary mononitrile NSC 148363 UNII-N2G72X091L is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 83.13 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.
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.
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.
