Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 276.29 g/mol gives Tanshinone I distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Tanshinone I (CAS 568-73-0), a certified reference material (molecular formula C18H12O3, MW 276.29 g/mol) for analytical method development and quality control.
Tanshinone I (C18H12O3) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 Tanshinone I 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.
