Antiseptic (chlorinated phenol)
Identity: Chloroxylenol
IUPAC name: 4-chloro-3,5-dimethylphenol
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.
Chromatographic purity and mg per unit by the method matched to the compound, identity against a reference standard. 1 unit.

Purity and quantity is $250 per sample (1 unit) and raw powder purity is $200 for 50 mg, with results in 3 to 5 business days. Send the material sealed and labeled, with the label claim and the form it contains.
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.
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.
It is also called PCMX or 4-chloro-3,5-dimethylphenol. All of these refer to the same compound.
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.
