Cyclobutyl isocyanide CAS 90993-55-8

Description

Compared with other compounds in its class, the molecular weight of 81.12 g/mol gives Cyclobutyl isocyanide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Cyclobutyl isocyanide (CAS 90993-55-8), molecular formula C5H7N and molecular weight 81.12 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C5H7N, Cyclobutyl isocyanide contains a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 81.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), Cyclobutyl isocyanide 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.
