Chemical Structure

(1S,2S,5R)-2-isopropyl-5-methylcyclohexane-1-carbonitrile CAS 180978-26-1 chemical structure

Description

As a certified reference material (CRM), (1S,2S,5R)-2-isopropyl-5-methylcyclohexane-1-carbonitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

(1S,2S,5R)-2-isopropyl-5-methylcyclohexane-1-carbonitrile (CAS 180978-26-1), molecular formula C11H19N and molecular weight 165.28 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (1S,2S,5R)-2-isopropyl-5-methylcyclohexane-1-carbonitrile (C11H19N) contains a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 165.28 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.
