Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 28308-00-1 Dichloro(N,N,N inverted exclamation marka,N inverted exclamation marka-tetramethylethane-1,2-diamine)zinc Dichloro(N,N,N inverted exclamation marka,N inverted exclamation marka-tetramethylethylenediamine)zinc ZnCl2-TMEDA.
28308-00-1 Dichloro(N,N,N inverted exclamation marka,N inverted exclamation marka-tetramethylethane-1,2-diamine)zinc Dichloro(N,N,N inverted exclamation marka,N inverted exclamation marka-tetramethylethylenediamine)zinc ZnCl2-TMEDA (CAS 28308-00-1), molecular formula Cl2ZnC6H16N2 and molecular weight 252.49 g/mol, is a CATO reference standard with documented purity and traceability.
28308-00-1 Dichloro(N,N,N inverted exclamation marka,N inverted exclamation marka-tetramethylethane-1,2-diamine)zinc Dichloro(N,N,N inverted exclamation marka,N inverted exclamation marka-tetramethylethylenediamine)zinc ZnCl2-TMEDA (Cl2ZnC6H16N2) contains a salt form, 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.
