Chemical Structure
Description
The occurrence of N-(9-Oxo-9H-fluoren-1-yl)acetamide is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(9-Oxo-9H-fluoren-1-yl)acetamide (CAS 6954-57-0), molecular formula C4H6ClNO2 and molecular weight 135.55 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N-(9-Oxo-9H-fluoren-1-yl)acetamide (C4H6ClNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 135.55 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
