Chemical Structure
Description
4-(Tert-butyl)-1,2-dichlorobenzene (CAS 18982-90-6), molecular formula C10H12Cl2 and molecular weight 203.11 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-(Tert-butyl)-1,2-dichlorobenzene (C10H12Cl2) contains chlorine substitution, an aromatic ring system. 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 203.11 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.
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), 4-(Tert-butyl)-1,2-dichlorobenzene 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.
