Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-chloro-2-methyl-5H-pyrrolo[3,2-d]pyrimidine.
CATO supplies 4-chloro-2-methyl-5H-pyrrolo[3,2-d]pyrimidine (CAS 65749-86-2), a certified reference material (molecular formula C7H14ClN3, MW 175.66 g/mol) for analytical method development and quality control.
The molecular framework of 4-chloro-2-methyl-5H-pyrrolo[3,2-d]pyrimidine (C7H14ClN3) is characterized by 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.
CATO manufactures 4-chloro-2-methyl-5H-pyrrolo[3,2-d]pyrimidine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
