| Health effects | Chronically high levels of methylmalonic acid are associated with at least 5 inborn errors of metabolism including: Malonyl CoA decarboxylase deficiency, Malonic Aciduria, Methylmalonate Semialdehyde Dehydrogenase Deficiency, Methylmalonic Aciduria and Methylmalonic Aciduria Due to Cobalamin-Related Disorders. |
| Toxicity summary | Methylmalonic acid is a vital intermediate in the metabolism of fat and protein. Abnormalities in methylmalonic acid metabolism lead to methylmalonic aciduria. This metabolic disease is attributed to a block in the enzymatic conversion of methylmalonyl CoA to succinyl CoA. Accumulation of Methylmalonic acid in the body has been shown to be toxic. |
| Carcinogen Classification | No indication of carcinogenicity to humans (not listed by IARC). |

Applications & Uses
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).
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.
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.
