3,4-Dichloro-N-(2,6-dioxotetrahydro-2H-pyran-3-yl)benzamide CAS 104252-86-0

Description

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.

CATO supplies 3,4-Dichloro-N-(2,6-dioxotetrahydro-2H-pyran-3-yl)benzamide (CAS 104252-86-0), a certified reference material (molecular formula C12H9Cl2NO4, MW 302.11 g/mol) for analytical method development and quality control.

The molecular framework of 3,4-Dichloro-N-(2,6-dioxotetrahydro-2H-pyran-3-yl)benzamide (C12H9Cl2NO4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
