Compared with other compounds in its class, the molecular weight of 258.34 g/mol gives (+)-Biotin Methyl Ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(+)-Biotin Methyl Ester (CAS 608-16-2), molecular formula C11H18N2O3S and molecular weight 258.34 g/mol, is a CATO reference standard with documented purity and traceability.
(+)-Biotin Methyl Ester (C11H18N2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 (+)-Biotin Methyl Ester 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.
