Chemical Structure
Description
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.
CATO supplies 5-(Indolin-5-yl)-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine dihydrochloride (CAS 1337533-85-3), a certified reference material (molecular formula C15H15N5HCl, MW 301.78 g/mol) for analytical method development and quality control.
Based on its molecular formula C15H15N5HCl, 5-(Indolin-5-yl)-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine dihydrochloride 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 301.78 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 5-(Indolin-5-yl)-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine dihydrochloride 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.
