7-Aminoflunitrazepam-13C6,
|
A-111
|
100 µg/mL in Acetonitrile
This stable-labeled internal standard is suitable for quantitation of 7-aminoflunitrazepam levels by LC-MS/MS methods for clinical toxicology, forensic analysis, urine drug testing, pain prescription monitoring or isotope dilution applications. 7-Aminoflunitrazepam is a major urinary metabolite of flunitrazepam, sold under the trade name Rohypnol. Flunitrazepam is an intermediate-acting benzodiazepine prescribed for the treatment of severe insomnia. For these analyses, 13C-labeled internal standards can eliminate potential issues of isotopic exchange and minimize separation of later-eluting analytes from a higher substituted deuterium-labeled internal standard.

F-044
|
100 ug/mL in Methanol
Flurazepam is a long acting benzodiazepine that is used to treat mild to moderate insomnia. This stable-labeled internal standard is suitable for quantitation of flurazepam levels in GC/MS or LC/MS methods for clinical toxicology, forensic analysis, urine drug testing, pain prescription monitoring or isotope dilution applications.
