Chemical Structure

(9H-Fluoren-9-yl)methyl (S)-(4-hydroxybutan-2-yl)carbamate CAS 1221274-40-3 chemical structure

Description

The occurrence of (9H-Fluoren-9-yl)methyl (S)-(4-hydroxybutan-2-yl)carbamate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(9H-Fluoren-9-yl)methyl (S)-(4-hydroxybutan-2-yl)carbamate (CAS 1221274-40-3), molecular formula C19H21NO3 and molecular weight 311.37 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (9H-Fluoren-9-yl)methyl (S)-(4-hydroxybutan-2-yl)carbamate (C19H21NO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

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.
