Production method of this chemical: DL-glyceraldehyde dimethyl acetal could react to produce 2,2-Dimethoxyacetaldehyde. This reaction could happen in the presence of the reagent of aq. NaIO₄ and the solvent of CH₂Cl₂, and it needs one hour to react in the ambient temperature.

Use of this chemical: 2,2-Dimethoxyacetaldehyde could react with N,N-dimethyl-hydrazine to produce 2,2-dimethoxyethanal dimethylhydrazone. This reaction could happen in the presence of the reagent of K₂CO₃and the solvent of H₂O, and it needs 2 hours to react.

When you are dealing with this chemical, you should be careful. For one thing, it is irritant which may cause inflammation to the skin or other mucous membranes. This chemical is irritating to skin and may cause sensitisation by skin contact. For another thing, it is highly flammable which may catch fire in contact with air, only needing brief contact with an ignition source, and it has a very low flash point or evolve highly flammable gases in contact with water. Therefore, you should wear suitable protective clothing and gloves and then avoid contacting with skin. Then remember to keep it away from sources of ignition - No smoking.

In addition, you could convert the following datas into the molecular structure:
(1)Canonical SMILES: COC(C=O)OC
(2)InChI: InChI=1S/C4H8O3/c1-6-4(3-5)7-2/h3-4H,1-2H3
(3)InChIKey: OGFKTAMJLKHRAZ-UHFFFAOYSA-N
