Chemical Structure
Description
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.
2-Cyclopropyl-1H-1,3-benzodiazole-5-carboxylic acid hydrochloride (CAS 2097935-54-9), molecular formula C11H10N2O2HCl and molecular weight 238.67 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H10N2O2HCl, 2-Cyclopropyl-1H-1,3-benzodiazole-5-carboxylic acid hydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 238.67 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 2-Cyclopropyl-1H-1,3-benzodiazole-5-carboxylic acid 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.
