Description
As a certified reference material (CRM), 3-(Dichloromethyl)benzoyl Chloride 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.
3-(Dichloromethyl)benzoyl Chloride (CAS 36747-51-0) is a high-purity analytical reference standard with the molecular formula C8H5Cl3O and a molecular weight of 223.48 g/mol.
Based on its molecular formula C8H5Cl3O, 3-(Dichloromethyl)benzoyl Chloride 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 223.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
