MWB0804EO7 7783-90-6 Silver chloride Silver chloride (AgCl) Caswell No. 735A EINECS 232-033-3 EPA Pesticide Chemical Code 072506 Silver(I) chloride Silver monochloride Mark II UNII-MWB0804EO7 EC 232-033-3 (CAS 7783-90-6), molecular formula AgCl and molecular weight 143.32 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, MWB0804EO7 7783-90-6 Silver chloride Silver chloride (AgCl) Caswell No. 735A EINECS 232-033-3 EPA Pesticide Chemical Code 072506 Silver(I) chloride Silver monochloride Mark II UNII-MWB0804EO7 EC 232-033-3 (AgCl) contains chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 143.32 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.
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.
