delta1-Cortienic acid

It features adelta1 double bond in the A-ring and a terminal carboxylic acid side chain, making it a key building block for glucocorticoids such as prednisolone- and prednisone-type compounds. It is valued in API manufacturing for enabling controlled side-chain modifications and functional group transformations during corticosteroid synthesis. delta1-Cortienic acid is a steroidal carboxylic acid intermediate employed to synthesize corticosteroid active pharmaceutical ingredients (APIs).
