Cyclohexane

Cyclohexane is a non-polar cyclic hydrocarbon widely used as a solvent in chemical, pharmaceutical, and industrial applications. It has the molecular formula C₆H₁₂, a molecular weight of 84.16 g/mol, and is identified by CAS No. 110-82-7. Cyclohexane may be present as a residual solvent or process-related impurity in APIs, excipients, and finished drug products, requiring accurate and sensitive quantification.

Gas chromatographic analysis (GC-FID or GC-MS) is commonly used for cyclohexane determination. Laboratories rely on high-quality GC standards, GC calibration standards, and GC reference standards to ensure accurate quantification, traceability, and reproducibility. Certified GC standards, GC analytical standards, and GC certified reference materials (GC CRM standards) provide validated reference values for method development, system suitability, and regulatory compliance. Ready-to-use GC calibration solutions and GC standard solutions simplify instrument calibration, method validation, and routine quality control.
