Chemical Structure
Description
The molecular framework of 4-[(ethylamino)methyl]-5-(hydroxymethyl)-2-methylpyridin-3-ol dihydrochloride (C10H16N2O2HCl) 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.
4-[(ethylamino)methyl]-5-(hydroxymethyl)-2-methylpyridin-3-ol dihydrochloride (CAS 1909336-49-7), molecular formula C10H16N2O2HCl and molecular weight 232.71 g/mol, is a CATO reference standard with documented purity and traceability.
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.
