    Product Description

    Tin (2+) Oxalate CAS 814-94-8 is an inorganic tin(II) salt, also known as stannous oxalate or tin(II) oxalate, with molecular formula C2O4Sn, molecular weight about 206.73 and EINECS 212-414-0.

    Synonyms: Stannous oxalate; Tin(II) oxalate; Tin ethanedioate; Oxalato tin.

    CAS: 814-94-8.

    It has the molecular formula C2O4Sn and a molecular weight of about 206.73 g/mol.

    It appears as a white to off-white crystalline or free-flowing powder.

    It gives high catalytic activity in esterification, transesterification and polycondensation reactions.

    It produces light-colored, color-stable esters with low side-reaction tendency.

    Its high tin content makes it suitable for polyester polyols, plasticizers, nonionic surfactants and specialty polymers such as PTT.

    It has a high metal content, low color contribution and a lower toxicity profile than many organotin alternatives.

    It is noncorrosive and can be easily removed from the reaction mixture by chemical treatment or adsorption after esterification.

    It is practically insoluble in water and alcohol, but soluble in dilute acids such as hydrochloric acid.

    In esterification processes the typical dosage is about 0.01–0.2% by weight, with high reactivity generally above 160 °C.

    Store in a cool, dry, well-ventilated area in tightly closed containers away from moisture and heat.

    Protect from moisture and keep containers closed when not in use.

    Confirm appearance, tin content, purity, moisture and grade as required.

    Use suitable dust and eye protection during handling, and wash skin contact with soap and water.

    Confirm packaging with the requested quantity and destination requirements.

    FAQ - Technical & Supply Chain

    • Q:

      What is Tin (2+) Oxalate CAS 814-94-8?

      A: It is an inorganic tin(II) salt, also called stannous oxalate, with the formula C2O4Sn and a molecular weight of about 206.73 g/mol. It is supplied as a white to off-white crystalline or free-flowing powder and is used mainly as an esterification and transesterification catalyst.
    • Q:

      Why is stannous oxalate used in polyester and plasticizer production?

      A: It gives high catalytic activity in esterification, transesterification, and polycondensation reactions while producing light-colored, color-stable esters. Its high tin content and low side-reaction tendency make it suitable for polyester polyols, plasticizers, nonionic surfactants, and PTT or specialty polymers.
    • Q:

      How does Tin (2+) Oxalate compare with organotin catalysts?

      A: It has a high metal content, low color contribution, and a lower toxicity profile than many organotin alternatives. It is noncorrosive and can be easily removed from the reaction mixture by chemical treatment or adsorption after esterification.
    • Q:

      Is Stannous Oxalate soluble in water, and how is it normally dosed?

      A: It is practically insoluble in water and alcohol, but soluble in dilute acids such as hydrochloric acid. In esterification processes the typical dosage is about 0.01-0.2% by weight, with high reactivity generally obtained above 160 degrees C.
    • Q:

      What are the non-catalyst applications of Tin (2+) Oxalate?

      A: It is used as a mordant in textile dyeing and printing, in stannous oral-care compositions, and as a reducing agent in specialized photographic developer formulations. It also appears in coal hydrogenation and selected metallurgical recovery applications.
