Chemical Structure

20781-20-8 2,4-Dimethoxybenzylamine Benzenemethanamine, 2,4-dimethoxy- CAS 20781-20-8 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 20781-20-8 2,4-Dimethoxybenzylamine Benzenemethanamine, 2,4-dimethoxy- (CAS 20781-20-8), a certified reference material (molecular formula C9H19NO2, MW 173.25 g/mol) for analytical method development and quality control.

20781-20-8 2,4-Dimethoxybenzylamine Benzenemethanamine, 2,4-dimethoxy- (C9H19NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
