Chemical Structure

Aluminum selenide CAS 1302-82-5 chemical structure

Description

The occurrence of Aluminum selenide is closely related to an inorganic composition in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Aluminum selenide (CAS 1302-82-5), a certified reference material (molecular formula Al2Se3, MW 290.84 g/mol) for analytical method development and quality control.

Structurally, Aluminum selenide (Al2Se3) 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 290.84 g/mol, it falls into the medium-molecular-weight range.

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
