Chemical Structure
Description
Methyl 6-methyl-1-oxo-2,3-dihydro-1h-indene-2-carboxylate (CAS 183545-63-3), molecular formula C12H12O3 and molecular weight 204.22 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Methyl 6-methyl-1-oxo-2,3-dihydro-1h-indene-2-carboxylate (C12H12O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 204.22 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Methyl 6-methyl-1-oxo-2,3-dihydro-1h-indene-2-carboxylate 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.
