Chemical Structure

Malonic Acid CAS 141-82-2 chemical structure

Description

The occurrence of Malonic Acid is closely related to a carboxylic acid group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Malonic Acid (CAS 141-82-2), molecular formula C3H4O4 and molecular weight 104.06 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, an ether linkage, Malonic Acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 104.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Malonic Acid 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.
