1996-41-4 6,8,9,13-tetrahydroxy-5,15-dimethyl-3,3a,5,8,9,10,11,13b-octahydro-2h-11,8-(epoxymethano)furo[3,2-c]naphtho[2,3-g]isochromene-2,7,12-trione AR-1H0444 CAS 1996-41-4

Description

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.

1996-41-4 6,8,9,13-tetrahydroxy-5,15-dimethyl-3,3a,5,8,9,10,11,13b-octahydro-2h-11,8-(epoxymethano)furo[3,2-c]naphtho[2,3-g]isochromene-2,7,12-trione AR-1H0444 (CAS 1996-41-4) is a high-purity analytical reference standard with the molecular formula C6H10ClFO and a molecular weight of 152.59 g/mol.

The molecular framework of 1996-41-4 6,8,9,13-tetrahydroxy-5,15-dimethyl-3,3a,5,8,9,10,11,13b-octahydro-2h-11,8-(epoxymethano)furo[3,2-c]naphtho[2,3-g]isochromene-2,7,12-trione AR-1H0444 (C6H10ClFO) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
