1-tert-butyl-4-chloro-1H-pyrazolo[3,4-d]pyrimidine (CAS 1100365-45-4), molecular formula C9H19ClN4 and molecular weight 218.73 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-tert-butyl-4-chloro-1H-pyrazolo[3,4-d]pyrimidine (C9H19ClN4) 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 1-tert-butyl-4-chloro-1H-pyrazolo[3,4-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.
