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 3,4-Difluoro-3-(3-pyrrolinomethyl) benzophenone.
CATO supplies 3,4-Difluoro-3-(3-pyrrolinomethyl) benzophenone (CAS 898749-60-5), a certified reference material (molecular formula C18H15F2NO, MW 299.31 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 3,4-Difluoro-3-(3-pyrrolinomethyl) benzophenone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 299.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 3,4-Difluoro-3-(3-pyrrolinomethyl) benzophenone 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.
