Chemical Structure

5-(Methyl-d3)tetrahydrofolic Acid (Mixture of Diastereomers) CAS 1356019-97-0 chemical structure

Description

As a certified reference material (CRM), 5-(Methyl-d3)tetrahydrofolic Acid (Mixture of Diastereomers) 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.

5-(Methyl-d3)tetrahydrofolic Acid (Mixture of Diastereomers) (CAS 1356019-97-0) is a high-purity analytical reference standard with the molecular formula C20H22D3N7O6 and a molecular weight of 462.47 g/mol.

Owing to deuterium isotope labeling, a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 5-(Methyl-d3)tetrahydrofolic Acid (Mixture of Diastereomers) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 462.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
