Chemical Structure

Dipropyl malonate CAS 1117-19-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Dipropyl malonate.

Dipropyl malonate (CAS 1117-19-7) is a high-purity analytical reference standard with the molecular formula C9H16O4 and a molecular weight of 188.22 g/mol.

Based on its molecular formula C9H16O4, Dipropyl malonate contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 188.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
