Chemical Structure
Description
The occurrence of Quinmerac-13C6 is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Quinmerac-13C6 (CAS 1185039-71-7) is a high-purity analytical reference standard with the molecular formula C5[13C]6H8ClNO2 and a molecular weight of 227.60 g/mol.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Quinmerac-13C6 is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 227.60 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), Quinmerac-13C6 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.
