Chemical Structure
Description
As a certified reference material (CRM), 1,2,3,4-Tetrahydropyrimido[1,2-α]indole HCl 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.
CATO supplies 1,2,3,4-Tetrahydropyrimido[1,2-α]indole HCl (CAS 42456-83-7), a certified reference material (molecular formula C11H12N2HCl, MW 208.69 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H12N2HCl, 1,2,3,4-Tetrahydropyrimido[1,2-α]indole HCl contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 208.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
