Chemical Structure

Acetoacetic Acid Methyl Ester CAS 105-45-3 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.

Acetoacetic Acid Methyl Ester (CAS 105-45-3), molecular formula C5H8O3 and molecular weight 116.12 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Acetoacetic Acid Methyl Ester (C5H8O3) 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 116.12 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.
