Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

1-(4-Fluorophenyl)-5-((4-hydroxypiperidin-4-yl)methyl)-1,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one hydrochloride (CAS 1959555-01-1), molecular formula C17H18FN5O2HCl and molecular weight 379.82 g/mol, is a CATO reference standard with documented purity and traceability.

1-(4-Fluorophenyl)-5-((4-hydroxypiperidin-4-yl)methyl)-1,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one hydrochloride (C17H18FN5O2HCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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).

As a certified reference material (CRM), 1-(4-Fluorophenyl)-5-((4-hydroxypiperidin-4-yl)methyl)-1,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one hydrochloride 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.
