Advance Intermediates

Intermediates

Saving you time and cost with our selection of high-quality intermediates

Flavine under­stands the chal­leng­ing needs of API man­u­fac­tur­ers and offers an expen­sive pipeline of advance inter­me­di­ates that save pro­duc­tion cost and time. Our inter­me­di­ates are cru­cial pre­cur­sors to many com­mon API prod­ucts sold in the US and EU mar­kets. We also pro­vide cus­tom syn­the­sis of unique inter­me­di­ates and chem­i­cal compounds.

Our advance intermediates provide swift routes to key chemical classes:
