Chemical Structure
Description
The molecular framework of 4-Chloro-1h-pyrazolo[4,3-c]quinolin-3-amine (C10H7ClN4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
4-Chloro-1h-pyrazolo[4,3-c]quinolin-3-amine (CAS 156912-01-5) is a high-purity analytical reference standard with the molecular formula C10H7ClN4 and a molecular weight of 218.64 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-Chloro-1h-pyrazolo[4,3-c]quinolin-3-amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
