Chemical Structure
Description
The occurrence of 4,5-Dimethoxy-2-methylbenzeneethanamine HCl is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4,5-Dimethoxy-2-methylbenzeneethanamine HCl (CAS 55752-05-1) is a high-purity analytical reference standard with the molecular formula C11H17NO2HCl and a molecular weight of 231.72 g/mol.
The molecular framework of 4,5-Dimethoxy-2-methylbenzeneethanamine HCl (C11H17NO2HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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 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.
