Chemical Structure

Methylene Blue Hydrate CAS 122965-43-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 337.87 g/mol gives Methylene Blue Hydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methylene Blue Hydrate (CAS 122965-43-9) is a high-purity analytical reference standard with the molecular formula C16H18N3SClH2O and a molecular weight of 337.87 g/mol.

Based on its molecular formula C16H18N3SClH2O, Methylene Blue Hydrate contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 337.87 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
