| | 2-Methylpropanedioic acid Usage And Synthesis |
| Chemical Properties | white crystalline powder | | Uses | 2-Methylpropanedioic acid binds with coenzyme A to form methylmalonyl-CoA, also a metabolic intermediate transformed to succinic acid (SA) by a vitamin B12-dependent catalytic step, and is broadly used as a clinical biomarker of functional vitamin B12 status. | | Uses | Methylmalonic acid can be used as a substrate in:
- Esterification reactions by various catalysts.
- Synthesis of pyrimidinium betaines with formamidine.
- Synthesis of malonic acid half thioester (MAHT).
| | Definition | ChEBI:
Methylmalonic acid is a dicarboxylic acid that is malonic acid in which one of the methylene hydrogens is substituted by a methyl group. It has a role as a human metabolite. It is functionally related to a malonic acid. It is a conjugate acid of a methylmalonate(1-). | | Biological Functions | Methylmalonic acid is capable of diffusing out of cells in which it is being produced, so it may be detected in excess in the blood, CSF, and urine of patients with these various forms of the disease. | | General Description | Methylmalonic acid is an indicator of vitamin B12 deficiency and methylmalonic acidemia. This Certified Spiking Solution is suitable for use in preparation of calibrators or controls in clinical and diagnostic testing using GC/MS or LC/MS. | | storage | Store at RT | | Purification Methods | The acid crystallises as the hydrate from water.
