5-α-Cholestane is supplied as a certified reference material (CRM) prepared at a concentration of 10 mg/mL in chloroform. This single-component calibration standard is commonly used in analytical chemistry laboratories for instrument calibration, analytical method validation, and quality control procedures.

This reference material is suitable for chromatographic techniques including gas chromatography (GC) and high-performance liquid chromatography (HPLC). Laboratories use sterol standards such as 5-α-cholestane for calibration and verification of analytical methods used in lipid analysis, sterol quantification, and related analytical workflows.

The material is produced under the TraceCERT® reference material program and is supplied with a certificate of analysis supporting traceability and analytical verification. Certified reference materials such as this are used in regulated laboratory environments to support method validation, instrument performance verification, and analytical quality control.

Typical laboratories using this CRM include food and beverage testing laboratories, natural product research laboratories, academic research institutions, and government regulatory laboratories performing sterol analysis and analytical quality assurance.

This certified reference material is supplied with a certificate of analysis providing traceable concentration values suitable for calibration, method validation, and analytical quality control.

Shipping and Storage Notice

Please note that shipping and long-term storage conditions for certified reference materials may differ. Manufacturers determine the most appropriate shipping method based on product stability and shipping studies. Some CRM standards may ship at ambient temperature even though recommended long-term storage conditions are refrigerated or frozen. This does not affect product integrity when handled according to the manufacturer’s certificate of analysis and storage instructions.
