2-Chloro-4-isobutyl-6,7-dihydro-5H-cyclopenta[b]pyridine-3-carbonitrile CAS 1774903-21-7 chemical structure

Description

The occurrence of 2-Chloro-4-isobutyl-6,7-dihydro-5H-cyclopenta[b]pyridine-3-carbonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-Chloro-4-isobutyl-6,7-dihydro-5H-cyclopenta[b]pyridine-3-carbonitrile (CAS 1774903-21-7), a certified reference material (molecular formula C13H15ClN2, MW 234.72 g/mol) for analytical method development and quality control.

Structurally, 2-Chloro-4-isobutyl-6,7-dihydro-5H-cyclopenta[b]pyridine-3-carbonitrile (C13H15ClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 234.72 g/mol, it falls into the medium-molecular-weight range. 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 2-Chloro-4-isobutyl-6,7-dihydro-5H-cyclopenta[b]pyridine-3-carbonitrile 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.
