Chemical Structure

Alumina CAS 1344-28-1 chemical structure

Description

Structurally, Alumina (Al2O3) contains an inorganic composition. The molecule exhibits a degree of unsaturation (DBE) of 0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 101.96 g/mol, it falls into the low-molecular-weight range.

Alumina (CAS 1344-28-1), molecular formula Al2O3 and molecular weight 101.96 g/mol, is a CATO reference standard with documented purity and traceability.

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), Alumina 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.
