Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 505076-71-1 9H-fluoren-9-ylmethyl N-[(1S)-1-[methoxy(methyl)carbamoyl]-2-[(triphenylmethyl)carbamoyl]ethyl]carbamate KS-000023U5.

505076-71-1 9H-fluoren-9-ylmethyl N-[(1S)-1-[methoxy(methyl)carbamoyl]-2-[(triphenylmethyl)carbamoyl]ethyl]carbamate KS-000023U5 (CAS 505076-71-1) is a high-purity analytical reference standard with the molecular formula C40H37N3O5 and a molecular weight of 639.74 g/mol.

Structurally, 505076-71-1 9H-fluoren-9-ylmethyl N-[(1S)-1-[methoxy(methyl)carbamoyl]-2-[(triphenylmethyl)carbamoyl]ethyl]carbamate KS-000023U5 (C40H37N3O5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 24.0, corresponding to approximately 24 ring(s) or double-bond equivalent(s). With a molecular weight of 639.74 g/mol, it falls into the high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
