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 1-{[(9H-fluoren-9-ylmethoxy)carbonyl]amino}-4-phenylcyclohexane-1-carboxylic acid.
1-{[(9H-fluoren-9-ylmethoxy)carbonyl]amino}-4-phenylcyclohexane-1-carboxylic acid (CAS 851307-75-0), molecular formula C28H27NO4 and molecular weight 441.52 g/mol, is a CATO reference standard with documented purity and traceability.
1-{[(9H-fluoren-9-ylmethoxy)carbonyl]amino}-4-phenylcyclohexane-1-carboxylic acid (C28H27NO4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
