Description
CATO manufactures 4-Pyridineacetyl chloride 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.
4-Pyridineacetyl chloride hydrochloride (CAS 39685-78-4), molecular formula C7H6ClNOHCl and molecular weight 192.04 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Pyridineacetyl chloride hydrochloride (C7H6ClNOHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 192.04 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.
