Ingredient technology · CAS 497-30-3
US-synthesized or Mironova-purified fermentation-derived L-ergothioneine, with lot-specific analytical data and technical support for your formulation.
Supply routes
Both offerings deliver L-ergothioneine, CAS 497-30-3. Their differences lie in production, impurity controls, and documentation. Our team helps you select by application and destination market.
EGT-S · US synthesis
A defined chemical route, with control from starting materials through final release at our Fairfield, New Jersey facility.
Synthesized and released in Fairfield, New Jersey.
Discuss EGT-SEGT-F · Purification and batch testing
Fermentation-derived material, extensively purified and recrystallized by Mironova, with finished-batch testing before QA release.
Purified and finished in the USA from imported fermentation-derived L-ergothioneine.
Discuss EGT-FSpecifications, certificates and commercial information are available to approved buyers on request.
The Mironova contribution
Fermentation-derived EGT requires downstream purification and residue verification. Mironova carries out that work in Fairfield: purification, recrystallization, finished-batch testing, and QA review.
Every finished EGT-F batch undergoes PicoGreen residual dsDNA analysis and USP microbial limits testing, with method suitability in the EGT matrix.
Imported fermentation-derived L-ergothioneine is quarantined and identity-verified at Fairfield, New Jersey. Mironova does not ferment.
Mironova extensively purifies and recrystallizes the imported material, then finishes and packages it in Fairfield, New Jersey.
PicoGreen residual dsDNA analysis and USP <61>/<62> microbial limits testing include method suitability in the EGT matrix. The release panel also includes endotoxin and host-cell-protein testing.
QA reviews finished-batch results against PS-EGT-F Rev. 4. Each batch CoA reports the measured residual dsDNA value and microbial results.
Qualification essentials
Both offerings are released against defined specifications. Your shipment is supported by its own certificate of analysis; EGT-F includes additional residue and microbial batch documentation.
Follow the lot-specific handling instructions and re-test date supplied with your shipment.
