Chemical Structure
Description
The occurrence of 2-Benzyl-4-Chlorophenol is closely related to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Benzyl-4-Chlorophenol (CAS 120-32-1), molecular formula C13H11ClO and molecular weight 218.68 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H11ClO, 2-Benzyl-4-Chlorophenol contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 218.68 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Benzyl-4-Chlorophenol 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.
