Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 182.23 g/mol gives L-Citrulline-d7 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies L-Citrulline-d7 (CAS 2483831-24-7), a certified reference material (molecular formula C6H6D7N3O3, MW 182.23 g/mol) for analytical method development and quality control.
Owing to deuterium isotope labeling, an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, L-Citrulline-d7 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.23 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.
As a certified reference material (CRM), L-Citrulline-d7 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.
