Chemical Structure

N-Acetyl-N-(9H-fluoren-2-yl)acetamide CAS 642-65-9 chemical structure

Description

N-Acetyl-N-(9H-fluoren-2-yl)acetamide (CAS 642-65-9) is a high-purity analytical reference standard with the molecular formula C17H15NO2 and a molecular weight of 265.31 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, N-Acetyl-N-(9H-fluoren-2-yl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 265.31 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), N-Acetyl-N-(9H-fluoren-2-yl)acetamide 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.
