Chemical Structure
Description
As a certified reference material (CRM), Poly(oxy-1,2-ethanediyl), .alpha.-(2-chloroethyl)-.omega.-(2-chloroethoxy)- 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.
Poly(oxy-1,2-ethanediyl), .alpha.-(2-chloroethyl)-.omega.-(2-chloroethoxy)- (CAS 27252-69-3), molecular formula C6H12Cl2O2 and molecular weight 187.06 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Poly(oxy-1,2-ethanediyl), .alpha.-(2-chloroethyl)-.omega.-(2-chloroethoxy)- (C6H12Cl2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
