IUPAC name: (1S,2R,13R,14S,17R,18S)-17-ethynyl-2,18-dimethyl-7-oxa-6-azapentacyclo[11.7.0.02,10.04,8.014,18]icosa-4(8),5,9-trien-17-ol

How Vanguard tests Danazol

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

The USP monograph covers identity by infrared and UV spectroscopy, specific rotation, chromatographic purity by thin-layer chromatography, assay by UV spectrophotometry, and loss on drying. Full testing to the USP Danazol 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 Danazol testing

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

No. The $250 test covers identity, purity and quantity by HPLC with UV detection for purity and assay, and LC-MS for identity. Full testing to the USP Danazol monograph is available and quoted.

Danazol has an isoxazole ring. Does that affect testing?

It gives danazol a distinct UV spectrum and a nitrogen-containing mass, which makes LC-MS identity straightforward compared with plain steroids.

What form do danazol samples usually arrive in?

Usually a white to pale yellow powder or capsules. For capsules, send the labeled amount per capsule so the quantity can be reported against it.
