Description
CATO manufactures 2,2-Bis(chloromethyl)oxirane 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.
CATO supplies 2,2-Bis(chloromethyl)oxirane (CAS 1003-20-9), a certified reference material (molecular formula C4H6Cl2O, MW 141.00 g/mol) for analytical method development and quality control.
Structurally, 2,2-Bis(chloromethyl)oxirane (C4H6Cl2O) contains a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 141.00 g/mol, it falls into the low-molecular-weight range. 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.
