## Abstract The derivatization method of thiazolidine‐4‐carboxylic acid (TZCA) and methyl‐thiazolidine‐4‐carboxylic acid (Me‐TZCA) in urine with alcohol/chloroformate was achieved. TZCA and Me‐TZCA were derivatized in one step in urine with ethyl chloroformate in 1 min at room temperature. The deri
