Chemical Structure

Calcium Oxide CAS 1305-78-8 chemical structure

Description

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

Calcium Oxide (CAS 1305-78-8), molecular formula CaO and molecular weight 56.08 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Calcium Oxide (CaO) 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 56.08 g/mol, it falls into the low-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.
