Chemical Structure
Description
As a certified reference material (CRM), 6-Chloro-2,4,7-trimethyl-7H-pyrrolo[2,3-d]pyrimidine 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 6-Chloro-2,4,7-trimethyl-7H-pyrrolo[2,3-d]pyrimidine (CAS 14352-34-2), a certified reference material (molecular formula C9H10ClN3, MW 195.65 g/mol) for analytical method development and quality control.
The molecular framework of 6-Chloro-2,4,7-trimethyl-7H-pyrrolo[2,3-d]pyrimidine (C9H10ClN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
