Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tetrahydrofolic Acid-13C5.
CATO supplies Tetrahydrofolic Acid-13C5 (CAS CATO-C4X-139519), a certified reference material (molecular formula C14[13C]5H23N7O6, MW 450.39 g/mol) for analytical method development and quality control.
The molecular framework of Tetrahydrofolic Acid-13C5 (C14[13C]5H23N7O6) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Tetrahydrofolic Acid-13C5 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.
