Chemical Structure

malonic acid dibutyl ester CAS 1190-39-2 chemical structure

Description

malonic acid dibutyl ester (CAS 1190-39-2), molecular formula C11H20O4 and molecular weight 216.27 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H20O4, malonic acid dibutyl ester 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 216.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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

As a certified reference material (CRM), malonic acid dibutyl ester meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
