CRM-AZA3
Certified Calibration Solution for Azaspiracid-3
Azaspiracids (AZAs) are a class of shellfish toxins first discovered in Ireland in 1995 after a human
intoxication event linked to the consumption of shellfish [1,2]. AZAs possess unique spiro assemblies
with both carboxyl and amine moieties [3,4]. The origin of AZAs has been identified as the
dinoflagellate Azadinium spinosum [5]. Intoxication symptoms can include nausea, stomach cramps,
headache, vomiting and diarrhea. The maximum permissible total level of AZAs (AZA1, AZA2, and
AZA3) in shellfish is currently 0.16 mg/kg in whole tissue [6]. CRM-AZA3-b is a certified calibration
solution of AZA3 in methanol and is a replacement for CRM-AZA3, which was released in 2011.
