Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 165.02 g/mol gives 2-Chloropyridin-3-amine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Chloropyridin-3-amine hydrochloride (CAS 94770-75-9), molecular formula C5H5ClN2HCl and molecular weight 165.02 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Chloropyridin-3-amine hydrochloride (C5H5ClN2HCl) contains a nitrile group, 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 165.02 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 2-Chloropyridin-3-amine hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
