Chemical Structure

Calcium sulfate dihydrate CAS 10101-41-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Calcium sulfate dihydrate.

Calcium sulfate dihydrate (CAS 10101-41-4) is a high-purity analytical reference standard with the molecular formula O4SCaH2O and a molecular weight of 154.15 g/mol.

Based on its molecular formula O4SCaH2O, Calcium sulfate dihydrate contains a sulfone group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 154.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.

CATO manufactures Calcium sulfate dihydrate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
