Chemical Structure
Description
The occurrence of 2-Amino-5-(methyl-d3)-pyridine is closely related to deuterium isotope labeling, a nitrile group, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Amino-5-(methyl-d3)-pyridine (CAS 1185311-13-0), molecular formula C6H5D3N2 and molecular weight 111.16 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Amino-5-(methyl-d3)-pyridine (C6H5D3N2) contains deuterium isotope labeling, a nitrile group, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 111.16 g/mol, it falls into the low-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
