Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Vitamin K1-18O (Mixture of 1-18O and 4-18O) (CAS 79083-00-4), a certified reference material (molecular formula C31H46O2, MW 450.70 g/mol) for analytical method development and quality control.
Vitamin K1-18O (Mixture of 1-18O and 4-18O) (C31H46O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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).
As a certified reference material (CRM), Vitamin K1-18O (Mixture of 1-18O and 4-18O) 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.
