General description

An internal standard suitable for quantitation of phenobarbital levels in GC/MS or LC/MS applications for clinical toxicology, urine drug testing, or forensic analysis. Phenobarbital is a barbiturate used to treat all epileptic seizure types except for absence seizures. Phenobarbital is the oldest and most widely used anticonvulsant.

Application

  • Internal standard application strategies in mass spectrometry imaging by desorption electrospray ionization mass spectrometry: This study utilizes Phenobarbital-D5 as a stable isotope-labeled internal standard in mass spectrometry imaging, highlighting its critical role in enhancing the accuracy and reliability of quantitative measurements in complex biological samples, particularly in pharmacokinetic studies (Perez and Ifa, 2021).
  • Determination of barbiturates in hair samples by using a validated UHPLC-HRMS method: This research employs Phenobarbital-D5 to calibrate and validate an ultra-high performance liquid chromatography-high resolution mass spectrometry (UHPLC-HRMS) method, aimed at investigating drug-facilitated crimes. The study demonstrates the utility of deuterated standards like Phenobarbital-D5 in forensic toxicology to ensure accurate detection and quantification of drugs in forensic samples (Wen et al., 2022).
