Chemical Structure
Description
Structurally, 2,3-Difluoro-1-methyl-4-((1s,4r)-4-propylcyclohexyl)benzene (C16H22F2) contains fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 252.34 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).
2,3-Difluoro-1-methyl-4-((1s,4r)-4-propylcyclohexyl)benzene (CAS 1374975-29-7), molecular formula C16H22F2 and molecular weight 252.34 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
