Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Acetic (1-ethyl-1H-benzo[d]imidazol-2-yl)carbamic anhydride.
Acetic (1-ethyl-1H-benzo[d]imidazol-2-yl)carbamic anhydride (CAS 61712-65-0), molecular formula C12H13N3O3 and molecular weight 247.25 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Acetic (1-ethyl-1H-benzo[d]imidazol-2-yl)carbamic anhydride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 247.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), Acetic (1-ethyl-1H-benzo[d]imidazol-2-yl)carbamic anhydride 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.
