2,2 inverted exclamation marka-Oxydiacetyl chloride 21062-20-4 Diglycolyl chloride CAS 21062-20-4 chemical structure

Description

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.

2,2 inverted exclamation marka-Oxydiacetyl chloride 21062-20-4 Diglycolyl chloride (CAS 21062-20-4), molecular formula C4H4Cl2O3 and molecular weight 170.98 g/mol, is a CATO reference standard with documented purity and traceability.

2,2 inverted exclamation marka-Oxydiacetyl chloride 21062-20-4 Diglycolyl chloride (C4H4Cl2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO manufactures 2,2 inverted exclamation marka-Oxydiacetyl chloride 21062-20-4 Diglycolyl chloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
