3-Chloro-4-pyridylcycloheptyl ketone CAS 898785-24-5

Description

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-Chloro-4-pyridylcycloheptyl ketone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 445.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

3-Chloro-4-pyridylcycloheptyl ketone (CAS 898785-24-5), molecular formula C25H30Cl2N2O and molecular weight 445.42 g/mol, is a CATO reference standard with documented purity and traceability.

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-Chloro-4-pyridylcycloheptyl ketone 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.
