Chemical Structure
Description
As a certified reference material (CRM), 1-(2-Acetoxyethyl)-2-methyl-1H-benzo[d]imidazole-5-carboxylic acid 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-(2-Acetoxyethyl)-2-methyl-1H-benzo[d]imidazole-5-carboxylic acid (CAS 282091-90-1), molecular formula C13H14N2O4 and molecular weight 262.26 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1-(2-Acetoxyethyl)-2-methyl-1H-benzo[d]imidazole-5-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 262.26 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.
