Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Carboxy-α-methylbenzeneacetic Acid-d3.
3-Carboxy-α-methylbenzeneacetic Acid-d3 (CAS 1330265-71-8), molecular formula C10H7D3O4 and molecular weight 197.20 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Carboxy-α-methylbenzeneacetic Acid-d3 (C10H7D3O4) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.5, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 197.20 g/mol, it falls into the medium-molecular-weight range. 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), 3-Carboxy-α-methylbenzeneacetic Acid-d3 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.
