Chemical Structure
Description
2,3-Dihydro-1,4-benzodioxin-2-carboximidic Acid Ethyl Ester Hydrochloride (CAS 79944-55-1), molecular formula C11H13NO3HCl and molecular weight 243.69 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,3-Dihydro-1,4-benzodioxin-2-carboximidic Acid Ethyl Ester Hydrochloride (C11H13NO3HCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
