Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 409.48 g/mol gives Thiamine /Vitamin B1 Impurity 48 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Thiamine /Vitamin B1 Impurity 48 (CAS CATO-C4X-187348), a pharmacopoeial impurity reference standard (molecular formula C21H27N7O2, MW 409.48 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C21H27N7O2, Thiamine /Vitamin B1 Impurity 48 contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 409.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
As a certified reference material (CRM), Thiamine /Vitamin B1 Impurity 48 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
