Chemical Structure

(S)-(9H-Fluoren-9-yl)methyl (1-chloro-1-oxo-3-phenylpropan-2-yl)carbamate CAS 103321-57-9 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 (S)-(9H-Fluoren-9-yl)methyl (1-chloro-1-oxo-3-phenylpropan-2-yl)carbamate.

(S)-(9H-Fluoren-9-yl)methyl (1-chloro-1-oxo-3-phenylpropan-2-yl)carbamate (CAS 103321-57-9), molecular formula C24H20ClNO3 and molecular weight 405.87 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (S)-(9H-Fluoren-9-yl)methyl (1-chloro-1-oxo-3-phenylpropan-2-yl)carbamate (C24H20ClNO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 405.87 g/mol, it falls into the moderately-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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), (S)-(9H-Fluoren-9-yl)methyl (1-chloro-1-oxo-3-phenylpropan-2-yl)carbamate 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.
