Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Oxiranecarbonitrile, (chloromethyl)(difluoroamino)-, homopolymer.
2-Oxiranecarbonitrile, (chloromethyl)(difluoroamino)-, homopolymer (CAS 68239-02-1) is a high-purity analytical reference standard with the molecular formula C4H3ClF2N2O and a molecular weight of 168.53 g/mol.
2-Oxiranecarbonitrile, (chloromethyl)(difluoroamino)-, homopolymer (C4H3ClF2N2O) contains an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
