Chemical Structure
Description
As a certified reference material (CRM), trans-2-(3-Chlorophenyl)cyclopropanecarboxylic Acid 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.
trans-2-(3-Chlorophenyl)cyclopropanecarboxylic Acid (CAS 16633-45-7), molecular formula C10H9ClO2 and molecular weight 196.63 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, trans-2-(3-Chlorophenyl)cyclopropanecarboxylic Acid (C10H9ClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 196.63 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).
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.
