Chemical Structure

Celestite CAS 14291-02-2 chemical structure

Description

The occurrence of Celestite is closely related to a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Celestite (CAS 14291-02-2) is a high-purity analytical reference standard with the molecular formula O4SSr and a molecular weight of 183.68 g/mol.

Owing to a sulfone group, Celestite is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 183.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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), Celestite 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.
