593-87-3 CHEBI:132481 Guanidine monoacetate Guanidine, acetate (1:1) acetic acid--guanidine (1/1) amino(imino)methanaminium acetate guanidine acetate guanidinium acetate guanidinium monoacetate (CAS 593-87-3) is a high-purity analytical reference standard with the molecular formula C2H4O2CH5N3 and a molecular weight of 119.12 g/mol.
The molecular framework of 593-87-3 CHEBI:132481 Guanidine monoacetate Guanidine, acetate (1:1) acetic acid--guanidine (1/1) amino(imino)methanaminium acetate guanidine acetate guanidinium acetate guanidinium monoacetate (C2H4O2CH5N3) 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.
As a certified reference material (CRM), 593-87-3 CHEBI:132481 Guanidine monoacetate Guanidine, acetate (1:1) acetic acid--guanidine (1/1) amino(imino)methanaminium acetate guanidine acetate guanidinium acetate guanidinium monoacetate 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.
