Chemical Structure
Description
The occurrence of 5,7-Dichloro-3-isopropyl-1-methyl-1H-pyrazolo[4,3-d]pyrimidine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5,7-Dichloro-3-isopropyl-1-methyl-1H-pyrazolo[4,3-d]pyrimidine (CAS 1956325-13-5) is a high-purity analytical reference standard with the molecular formula C9H10Cl2N4 and a molecular weight of 245.11 g/mol.
5,7-Dichloro-3-isopropyl-1-methyl-1H-pyrazolo[4,3-d]pyrimidine (C9H10Cl2N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 5,7-Dichloro-3-isopropyl-1-methyl-1H-pyrazolo[4,3-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.
