Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,3,3-trimethyl-2-oxo-2,3-dihydro-1H-indole-5-carboxylic acid.
1,3,3-trimethyl-2-oxo-2,3-dihydro-1H-indole-5-carboxylic acid (CAS 896160-47-7) is a high-purity analytical reference standard with the molecular formula C12H19NO3 and a molecular weight of 225.28 g/mol.
Structurally, 1,3,3-trimethyl-2-oxo-2,3-dihydro-1H-indole-5-carboxylic acid (C12H19NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 225.28 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
