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 3,3A,4,5,6,7-hexahydro-2H-indole-2-carboxylic acid.
CATO supplies 3,3A,4,5,6,7-hexahydro-2H-indole-2-carboxylic acid (CAS 754141-46-3), a certified reference material (molecular formula C9H13NO2, MW 167.21 g/mol) for analytical method development and quality control.
Structurally, 3,3A,4,5,6,7-hexahydro-2H-indole-2-carboxylic acid (C9H13NO2) 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 167.21 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.
CATO manufactures 3,3A,4,5,6,7-hexahydro-2H-indole-2-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
