Chemical Structure

Methylene Blue Trihydrate CAS 7220-79-3 chemical structure

Description

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

CATO supplies Methylene Blue Trihydrate (CAS 7220-79-3), a certified reference material (molecular formula C16H18N3SClH2O, MW 337.87 g/mol) for analytical method development and quality control.

Based on its molecular formula C16H18N3SClH2O, Methylene Blue Trihydrate 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.

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 Methylene Blue Trihydrate 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.
