How Vanguard tests Plerixafor

Method for the $250 identity, purity and quantity test: Chromatographic assay, with detection selected for the compound, against a reference standard, with results in 3 to 5 business days.

The USP monograph covers identity by infrared spectroscopy and HPLC retention time, assay by HPLC, organic impurities by HPLC, a cyclam limit by HPLC after derivatization, residue on ignition, water content, bacterial endotoxins, and microbial enumeration and specified microorganisms. Full testing to the USP Plerixafor monograph is available and quoted.

What's reported

Purity, as percent of total peak area
Quantity, against the label claim
Identity, reported as match or no match against the reference standard

Questions about Plerixafor testing

Is the $250 test the same as USP monograph testing?

No. The $250 test covers identity, purity and quantity by a chromatographic assay, with detection selected for the compound. Full testing to the USP Plerixafor monograph is available and quoted.

Why is plerixafor hard to detect by UV?

Plerixafor is two linked cyclam rings with only one benzene ring, so the lab uses a detection method suited to the compound.

What is cyclam and why is it measured?

Cyclam is the macrocyclic amine building block used to make plerixafor. It has no chromophore, so the USP monograph derivatizes it before measuring it by HPLC.
