9H-fluoren-9-ylphosphonic acid CAS 6344-53-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 9H-fluoren-9-ylphosphonic acid.

CATO supplies 9H-fluoren-9-ylphosphonic acid (CAS 6344-53-2), a certified reference material (molecular formula C11H13N3O, MW 203.24 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 9H-fluoren-9-ylphosphonic acid is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 203.24 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
