Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(3,4-Dihydroxyphenyl)ethyl-1-13C-amine-15N HCl (CAS 369656-74-6), molecular formula C7[13C]H11[15N]O2 HCl and molecular weight 189.64 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(3,4-Dihydroxyphenyl)ethyl-1-13C-amine-15N HCl (C7[13C]H11[15N]O2 HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 189.64 g/mol, it falls into the medium-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.
