Chemical Structure

Strontium chloride dihydrate CAS 16056-95-4 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.

Strontium chloride dihydrate (CAS 16056-95-4), molecular formula SrClH2O and molecular weight 141.09 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula SrClH2O, Strontium chloride dihydrate contains chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 141.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
