Chemical Structure
Description
The occurrence of 3-Propionyl-2,3,4,5-tetrahydro-1h-benzo[d]azepine-7-sulfonyl chloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Propionyl-2,3,4,5-tetrahydro-1h-benzo[d]azepine-7-sulfonyl chloride (CAS 1334147-15-7), molecular formula C13H16ClNO3S and molecular weight 301.79 g/mol, is a CATO reference standard with documented purity and traceability.
3-Propionyl-2,3,4,5-tetrahydro-1h-benzo[d]azepine-7-sulfonyl chloride (C13H16ClNO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 3-Propionyl-2,3,4,5-tetrahydro-1h-benzo[d]azepine-7-sulfonyl chloride 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.
