Cerilliant - Model P-151-1ML -Alcohol

P-151-1ML PEth 16:0/18:1-D5 - 100 µg/mL (as free phosphate) in Methanol - Certified Reference Material. This stable-labeled internal standard is suitable for quantitation of PEth 16:0/18:1 in LC/MS or GC/MS applications. PEth 16:0/18:1, also known as phosphatidylethanol 16:0/18:1, is a sensitive and specific biomarker for alcohol use and abuse. Since the detection window of PEth 16:0/18:1 in blood is longer than that of ethyl glucuronide (EtG) or ethyl sulfate (EtS) in urine, measurement of blood PEth 16:0/18:1 level is routinely performed in clinical toxicology and forensic testing applications such as abstinence monitoring and workplace drug testing. PEth 16:0/18:1 has also been investigated as a biomarker to confirm prenatal alcohol exposure (PAE).
