Chemical Structure
Description
3-Bromo-6-phenylpyrazolo[1,5-a]pyrimidin-7-amine (CAS 1039364-82-3), molecular formula C12H9BrN4 and molecular weight 289.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Bromo-6-phenylpyrazolo[1,5-a]pyrimidin-7-amine (C12H9BrN4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 3-Bromo-6-phenylpyrazolo[1,5-a]pyrimidin-7-amine 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.
