(5-Ethynyl-2-methoxyphenyl)methanamine CAS 1872875-03-0

Description

The occurrence of (5-Ethynyl-2-methoxyphenyl)methanamine is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(5-Ethynyl-2-methoxyphenyl)methanamine (CAS 1872875-03-0), molecular formula C10H11NO and molecular weight 161.20 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (5-Ethynyl-2-methoxyphenyl)methanamine (C10H11NO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
