2-Methyl-2-(4-nitro-3-((phenylsulfonyl)methyl)phenyl)-1,3-dioxolane CAS 339276-49-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Methyl-2-(4-nitro-3-((phenylsulfonyl)methyl)phenyl)-1,3-dioxolane.

2-Methyl-2-(4-nitro-3-((phenylsulfonyl)methyl)phenyl)-1,3-dioxolane (CAS 339276-49-2) is a high-purity analytical reference standard with the molecular formula C17H17NO6S and a molecular weight of 363.38 g/mol.

2-Methyl-2-(4-nitro-3-((phenylsulfonyl)methyl)phenyl)-1,3-dioxolane (C17H17NO6S) contains a flavonoid core, an amide group, a sulfone 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.
