Chemical Structure

Lipoic Acid CAS 62-46-4 chemical structure

Description

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.

Lipoic Acid (CAS 62-46-4) is a high-purity analytical reference standard with the molecular formula C8H14O2S2 and a molecular weight of 206.33 g/mol.

Based on its molecular formula C8H14O2S2, Lipoic Acid contains a sulfone group, 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 206.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

As a certified reference material (CRM), Lipoic 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.
