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 1H-Pyrazolo[4,3-d]pyrimidine, 5-chloro-3-iodo-1-methyl- (CAS 2385055-97-8), a certified reference material (molecular formula C6H4ClIN4, MW 294.48 g/mol) for analytical method development and quality control.
The molecular framework of 1H-Pyrazolo[4,3-d]pyrimidine, 5-chloro-3-iodo-1-methyl- (C6H4ClIN4) is characterized by a nitrile group, chlorine/iodine substitution, an aromatic ring system. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 1H-Pyrazolo[4,3-d]pyrimidine, 5-chloro-3-iodo-1-methyl- 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.
