Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 185.65 g/mol gives 5-Methyl-2,3-dihydro-1-benzofuran-3-amine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-Methyl-2,3-dihydro-1-benzofuran-3-amine hydrochloride (CAS 669-44-3), a certified reference material (molecular formula C9H11NOHCl, MW 185.65 g/mol) for analytical method development and quality control.
5-Methyl-2,3-dihydro-1-benzofuran-3-amine hydrochloride (C9H11NOHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), 5-Methyl-2,3-dihydro-1-benzofuran-3-amine hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
