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 2-((2-Amino-9H-fluoren-9-yl)oxy)ethyl acetate.
CATO supplies 2-((2-Amino-9H-fluoren-9-yl)oxy)ethyl acetate (CAS 401643-05-8), a certified reference material (molecular formula C17H17NO3, MW 283.32 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2-((2-Amino-9H-fluoren-9-yl)oxy)ethyl acetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 283.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 2-((2-Amino-9H-fluoren-9-yl)oxy)ethyl acetate 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.
