4-acetylisoquinoline CAS 40570-74-9

Description

Compared with other compounds in its class, the molecular weight of 171.20 g/mol gives 4-acetylisoquinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-acetylisoquinoline (CAS 40570-74-9), molecular formula C11H9NO and molecular weight 171.20 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-acetylisoquinoline (C11H9NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 171.20 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
