Chemical Structure

Glycerol CAS 56-81-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 92.09 g/mol gives Glycerol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Glycerol (CAS 56-81-5), molecular formula C3H8O3 and molecular weight 92.09 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C3H8O3, Glycerol 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 92.09 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.

As a certified reference material (CRM), Glycerol 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.
