    L-Cysteine hydrochloride monohydrate (Cas 7048-04-6) Usage

    General descriptio

    L-Cysteine hydrochloride monohydrate is a versatile chemical compound with various applications in different industries. It is a monohydrate, which means it contains one molecule of water for every molecule of the compound.

    Chemical Properties

    white crystalline powder

    Uses

    L-Cysteine hydrochloride monohydrate is used as a precursor in the food industry. It is added to various food products, particularly baked goods, to improve their texture and appearance. It has been used in research to test its effectiveness as an inhibitor of enzymatic browning in apples. Enzymatic browning is the natural process of fruits and vegetables turning brown when exposed to air, and inhibitors like L-Cysteine can help prevent this. L-Cysteine hydrochloride monohydrate finds use in the pharmaceutical industry, although specific applications are not detailed. It may be employed as an ingredient in pharmaceutical formulations.

    Definition

    ChEBI: A hydrate that is the monohydrate form of L-cysteine hydrochloride.

    Biochem/physiol Actions

    NMDA glutamatergic receptor antagonist.

    Purification Methods

    Likely impurities are cystine and tyrosine. Crystallise the salt from MeOH by adding diethyl ether, or from hot 20% HCl. Dry it under vacuum over P2O5. Hygroscopic. [Beilstein 4 III 1580, 1600.]

    Some of the L-cysteine complexes are L-cysteine tartarate monohydrate [15], L-cysteine hydrochloride monohydrate [16, 17] and L-cysteine hydrochloride [18]. In the present investigation, attempts were made to grow single crystals of L-cysteine hydrochloride monohydrate (LCB) by slow solvent evaporation technique and characterization on single crystal X-ray diraction (XRD), UVvisible absorption, the Fourier transform infrared (FTIR) spectroscopy, microhardness, thermogravimetricdierential thermal analysis (TG-DTA), dierential scanning calorimetry (DSC), second harmonic generation and dielectric studies were done as well
