Chemical Structure
Description
The occurrence of 2,2’-Dichlorobenzoin is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,2’-Dichlorobenzoin (CAS 35190-16-0), a certified reference material (molecular formula C14H10Cl2O2, MW 281.13 g/mol) for analytical method development and quality control.
Structurally, 2,2’-Dichlorobenzoin (C14H10Cl2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 281.13 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 2,2’-Dichlorobenzoin 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.
