Chemical Structure

Vitamin Impurity 33 CAS 6381-77-7 chemical structure

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.

Vitamin Impurity 33 (CAS 6381-77-7) is a certified pharmaceutical impurity reference standard with the molecular formula C6H7O6NaH2O and a molecular weight of 216.12 g/mol.

Structurally, Vitamin Impurity 33 (C6H7O6NaH2O) contains a carbohydrate-derived structure. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 216.12 g/mol, it falls into the medium-molecular-weight range.

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.
