Chemical Structure

1-Hydroxyguanidine CAS 13115-21-4 chemical structure

Description

As a certified reference material (CRM), 1-Hydroxyguanidine 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.

1-Hydroxyguanidine (CAS 13115-21-4) is a high-purity analytical reference standard with the molecular formula CH5N3O and a molecular weight of 75.07 g/mol.

The molecular framework of 1-Hydroxyguanidine (CH5N3O) is characterized by a hydroxyl group. 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.
