Chemical Structure
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 Calcium Folinate (CAS 1492-18-8), a certified reference material (molecular formula C20H21N7O7Ca, MW 511.51 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Calcium Folinate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 511.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), Calcium Folinate 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.
