Chemical Structure

Ascorbic Acid Impurity 9 CAS 28119-61-1 chemical structure

Description

CATO supplies Ascorbic Acid Impurity 9 (CAS 28119-61-1), a certified reference material (molecular formula C4H6O3, MW 102.09 g/mol) for analytical method development and quality control.

Structurally, Ascorbic Acid Impurity 9 (C4H6O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. 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 102.09 g/mol, it falls into the low-molecular-weight range.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
