Chemical Structure

<SC>L</SC>-Citrulline-5-<SUP>13</SUP>C,5,5-d<SUB>2</SUB> CAS 1786429-99-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 178.19 g/mol gives <SC>L</SC>-Citrulline-5-<SUP>13</SUP>C,5,5-d<SUB>2</SUB> distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies <SC>L</SC>-Citrulline-5-<SUP>13</SUP>C,5,5-d<SUB>2</SUB> (CAS 1786429-99-9), a certified reference material (molecular formula C5[13C]H11D2N3O3, MW 178.19 g/mol) for analytical method development and quality control.

The molecular framework of <SC>L</SC>-Citrulline-5-<SUP>13</SUP>C,5,5-d<SUB>2</SUB> (C5[13C]H11D2N3O3) is characterized by deuterium isotope labeling, an amino-acid-derived structure, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), <SC>L</SC>-Citrulline-5-<SUP>13</SUP>C,5,5-d<SUB>2</SUB> 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.
