Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(1H-Benzo[d]imidazol-2-yl)guanidine acetate.
1-(1H-Benzo[d]imidazol-2-yl)guanidine acetate (CAS 197806-67-0) is a high-purity analytical reference standard with the molecular formula C8H9N5C2H4O2 and a molecular weight of 235.25 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 1-(1H-Benzo[d]imidazol-2-yl)guanidine acetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 235.25 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).
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), 1-(1H-Benzo[d]imidazol-2-yl)guanidine acetate 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.
