9-Methyl-9<I>H</I>-fluorene-9-carbonyl-<SUP>13</SUP>Chlorine chloride CAS 1072315-89-9 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 9-Methyl-9<I>H</I>-fluorene-9-carbonyl-<SUP>13</SUP>Chlorine chloride.

9-Methyl-9<I>H</I>-fluorene-9-carbonyl-<SUP>13</SUP>Chlorine chloride (CAS 1072315-89-9) is a high-purity analytical reference standard with the molecular formula C14[13C]H23ClO and a molecular weight of 255.79 g/mol.

9-Methyl-9<I>H</I>-fluorene-9-carbonyl-<SUP>13</SUP>Chlorine chloride (C14[13C]H23ClO) contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
