Methoxyamine hydrochloride
Methoxyamine hydrochloride (also known as O-methylhydroxylamine hydrochloride; Methoxyamine; Methoxyamine hydrochloride (OMHA), is an important medicine, pesticide intermediates. Its major applications are as follows:
- it can be used for color photography and film printing.
- it is used as a reducing agent in organic synthesis industry for preparation of oximes.
- the field of medicine: it can be used for the synthesis of second-generation cephalosporins antibiotics cefuroxime (ester), neopropene, norethindine and hydroxyurea.
- the field of pesticides: the synthesis of new efficient, low-toxicity bactericidal metominostrobin.
- It is mainly produced by sodium nitrite method in our country.
The similar compound of methoxyamine hydrochloride, the ethoxylamine hydrochloride is mainly used for the production of herbicides, oxycarbazone, diltiazem and other herbicides.
- Used as a methoxyamine reagent, also used in the production of the side chain of Cefuroxime and other new drugs
- Used for pesticide synthesis.
- Use for pharmaceuticals production
- Used for the preparation of O-methyloxime together with aldehydes or ketones.
Methoxamine hydrochloride, also known as methoxamine hydrochloride, O-methyl hydroxylamine hydrochloride. It is a white crystalline powder, and its fusing point is 149 ~ 152 DEG C, soluble in water, dissolved in alcohol, insoluble in ether and toluene, etc., and the solution is in acid. Methoxamine hydrochloride is an important chemical and medicine intermediate, can be used for the development and printing of color photography and film, and is widely used in the synthesis of medicine, functional dye, low-toxin farm chemicals, and new herbicides. Methoxamine hydrochloride is mainly used in the synthesis of s-generation cephalosporin product cephalofruxin in medical, and sulfamethoxazole; alkynes promise are bright, the synthesis of hydroxyurea, etc.; Agricultural chemicals aspect is then mainly used in the kresoxim-methyl of synthesizing efficient low toxicity.
White to very faintly yellow crystalline powder
Methoxylamine hydrochloride is used as a reagent in the preparation of O-methyl oximes from aldehydes. It is orally bioavailable small molecule inhibitor with potential adjuvant activity. It is also used as internal standard for prostaglandin assays by gas chromatography-mass spectrometry.
Methoxylamine is a methoxime derivative used as internal standard for Prostaglandin assays by gas chromatography-mass spectrometry
antineoplastic, hydroxymethyltransferase inhibitor
In aqueous solution, Methoxyammonium chloride behaves as an acid. Materials in this group are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
Flash point data for Methoxyammonium chloride are not available. Methoxyammonium chloride is probably combustible.
Crystallise the hydrochloride from absolute EtOH or EtOH by addition of diethyl ether. [Kovach et al. J Am Chem Soc 107 7360 1985, Beilstein 1 IV 1252.]
