Structure and names

IUPAC name: (2R,3R,4R,5R)-4-[(2R,3R,4R,5S,6R)-5-[(2R,3R,4S,5S,6R)-3,4-dihydroxy-6-methyl-5-[[(1S,4R,5S,6S)-4,5,6-trihydroxy-3-(hydroxymethyl)cyclohex-2-en-1-yl]amino]oxan-2-yl]oxy-3,4-dihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy-2,3,5,6-tetrahydroxyhexanal

How Vanguard tests Acarbose

Identity, purity and quantity are measured by a chromatographic assay, with detection selected for the compound, against a reference standard, $250 per sample with results in 3 to 5 business days. Finished products use the same approach, with sample preparation matched to the product.

Full testing to the USP Acarbose monograph is available and quoted: identification by infrared absorption and HPLC, assay by HPLC, and impurities by HPLC.

What's reported

Purity, as percent of total peak area
Quantity, in mg per serving or % w/w against the label

Salts, forms and compendial references

A USP monograph exists for Acarbose. Monograph testing is quoted.
Tell us the salt or form the label states, so quantity is reported on the same basis.
One page covers Acarbose and its salts and forms.

Questions about Acarbose testing

Acarbose absorbs little UV light. How is it measured?

By a chromatographic assay, with detection selected for the compound, against an acarbose reference standard.

Can you test it in a finished product?

Yes. Capsules, powders, gummies and liquids are measured with sample preparation matched to the product, and reported in mg per serving or % w/w against the label.

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

No. The $250 test covers identity, purity and quantity against a reference standard. Full testing to the USP Acarbose monograph adds the monograph's own tests and is quoted.
