Chemical Structure

N-Acetyl-2-naphthylamine CAS 581-97-5 chemical structure

Description

CATO manufactures N-Acetyl-2-naphthylamine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

N-Acetyl-2-naphthylamine (CAS 581-97-5), molecular formula C12H11NO and molecular weight 185.22 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, N-Acetyl-2-naphthylamine (C12H11NO) 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 185.22 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.

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.
