Chemical Structure

Ascorbic Acid Impurity 39 CAS 492-30-8 chemical structure

Description

Structurally, Ascorbic Acid Impurity 39 (C6H10O5) contains a carbohydrate-derived structure. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 162.14 g/mol, it falls into the medium-molecular-weight range.

CATO supplies Ascorbic Acid Impurity 39 (CAS 492-30-8), a pharmacopoeial impurity reference standard (molecular formula C6H10O5, MW 162.14 g/mol) used for the identification and quantification of trace impurities in APIs.

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.
