Description

Application

Thiamine hydrochloride has been used as a keratin salts medium supplement for culturing log-phase fungus.[1] It has also been used as a supplement of VB medium the minimal medium of Vogel and Bonner.[2]

Biochem/physiol Actions

Thiamine hydrochloride is a cheap, non-toxic and efficient catalyst for the synthesis of amidoalkyl naphthols.[3] It inhibits the production of shikonin derivatives by suspension cultures of Lithospermum erythrorhizon.[4] Additionally, thiamine hydrochloride addition to apple juice concentrates reduces its patulin content.[5]

Thiamine hydrochloride is a hydrochloride salt form of thiamine (Vitamin B₁). It is crucial for aerobic metabolism, cell growth, transmission of nerve impulses and acetylcholine synthesis.[6]
