DL-CITRULLINE CAS 627-77-0

Description

Compared with other compounds in its class, the molecular weight of 175.19 g/mol gives DL-CITRULLINE distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

DL-CITRULLINE (CAS 627-77-0), molecular formula C6H13N3O3 and molecular weight 175.19 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of DL-CITRULLINE (C6H13N3O3) is characterized by 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), DL-CITRULLINE 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.
