Chemical Structure
Description
8-Chloro-2-methyl-1H,2H,3H,4H,5H-pyrido[4,3-b]indole hydrochloride (CAS 3785-12-4), molecular formula C12H13ClN2HCl and molecular weight 257.16 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 8-Chloro-2-methyl-1H,2H,3H,4H,5H-pyrido[4,3-b]indole hydrochloride (C12H13ClN2HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 257.16 g/mol, it falls into the medium-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.
