Chemical Structure

Calcium Carbonate CAS 471-34-1 chemical structure

Description

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.

Calcium Carbonate (CAS 471-34-1) is a high-purity analytical reference standard with the molecular formula CO3Ca and a molecular weight of 100.09 g/mol.

Structurally, Calcium Carbonate (CO3Ca) contains an organic framework. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 100.09 g/mol, it falls into the low-molecular-weight range.

As a certified reference material (CRM), Calcium Carbonate 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.
