Compared with other compounds in its class, the molecular weight of 261.70 g/mol gives 3-Methyl-5-(morpholinomethyl)furan-2-carboxylic acid hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Methyl-5-(morpholinomethyl)furan-2-carboxylic acid hydrochloride (CAS 435342-23-7), molecular formula C11H15NO4HCl and molecular weight 261.70 g/mol, is a CATO reference standard with documented purity and traceability.
3-Methyl-5-(morpholinomethyl)furan-2-carboxylic acid hydrochloride (C11H15NO4HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
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.
