Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(3-(1H-Pyrrolo[2,3-b]pyridin-1-yl)propyl)-3-(4-fluorobenzyl)urea.
1-(3-(1H-Pyrrolo[2,3-b]pyridin-1-yl)propyl)-3-(4-fluorobenzyl)urea (CAS 1797745-36-8), molecular formula C18H19FN4O and molecular weight 326.37 g/mol, is a CATO reference standard with documented purity and traceability.
1-(3-(1H-Pyrrolo[2,3-b]pyridin-1-yl)propyl)-3-(4-fluorobenzyl)urea (C18H19FN4O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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).
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), 1-(3-(1H-Pyrrolo[2,3-b]pyridin-1-yl)propyl)-3-(4-fluorobenzyl)urea 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.
