Chemical Structure
Description
The occurrence of Glyceryl Trinitrate Impurity 7 is closely related to a sulfone group, a carboxylic acid group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Glyceryl Trinitrate Impurity 7 (CAS 861542-51-0), a pharmacopoeial impurity reference standard (molecular formula C3H8O9S2, MW 252.22 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Glyceryl Trinitrate Impurity 7 (C3H8O9S2) is characterized by a sulfone group, a carboxylic acid group, an ether linkage. 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.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
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.
