Chemical Structure

Coumarin 138, 95% CAS 62669-74-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 229.27 g/mol gives Coumarin 138, 95% distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Coumarin 138, 95% (CAS 62669-74-3), molecular formula C14H15NO2 and molecular weight 229.27 g/mol, is a CATO reference standard with documented purity and traceability.

Coumarin 138, 95% (C14H15NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 Coumarin 138, 95% 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.
