How Vanguard tests Chloroxylenol

Method for the $250 identity, purity and quantity test: GC-FID assay and purity, GC-MS identity, against a reference standard, with results in 3 to 5 business days.

The USP monograph covers identity by infrared spectroscopy and GC retention time, assay by GC with flame ionization, organic impurities and tetrachloroethylene by GC, iron, residue on ignition and water determination. Full testing to the USP Chloroxylenol 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
  • With monograph testing (quoted): the monograph’s tests against its limits

Questions about Chloroxylenol testing

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

No. The $250 test covers identity, purity and quantity by GC-FID for assay and purity, with GC-MS to confirm identity. Full testing to the USP Chloroxylenol monograph is available and quoted.

Why is chloroxylenol tested by GC?

Chloroxylenol is a small, volatile phenol, and the USP monograph uses GC for both assay and impurities. GC also separates its isomers and other chlorinated xylenols cleanly.

What other names does chloroxylenol go by?

It is also called PCMX or 4-chloro-3,5-dimethylphenol. All of these refer to the same compound.

What forms does chloroxylenol arrive in?

As a crystalline powder or in finished products such as liquid soaps and antiseptic solutions. Finished products need an extraction step, so tell us the form when you submit.
