Retinol-¹³C₃ is an isotope-labeled analog of vitamin A (retinol) supplied as a certified reference material (CRM) solution at 10 µg/mL in ethanol containing 0.1% (w/v) BHT as a stabilizer. This single-component standard is intended for use as an internal standard, calibration reference, or quality control material in quantitative analytical methods.

Isotope-labeled retinol standards are commonly used in LC-MS/MS workflows for accurate quantification of vitamin A in biological matrices, foods, nutritional products, and pharmaceutical preparations. The labeled compound compensates for matrix effects, extraction variability, and instrument response differences, supporting robust method validation and analytical quality assurance.

This CRM is suitable for method development, instrument calibration, proficiency testing, and regulatory compliance testing in clinical, food, nutraceutical, and research laboratories. It is produced under controlled conditions and supplied with documentation supporting traceability and analytical reliability.

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 data. 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 manufacturer documentation.
