Chemical Structure

Calcium methacrylate hydrate CAS 16809-88-4 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 methacrylate hydrate.

Calcium methacrylate hydrate (CAS 16809-88-4) is a high-purity analytical reference standard with the molecular formula C4H5O2CaH2O and a molecular weight of 143.18 g/mol.

Structurally, Calcium methacrylate hydrate (C4H5O2CaH2O) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.5, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 143.18 g/mol, it falls into the low-molecular-weight range.

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), Calcium methacrylate hydrate 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.
